Memantine is a medication used to treat moderate to severe Alzheimer's disease. It is a non-competitive NMDA receptor antagonist, which means it blocks the activity of the NMDA receptor. The NMDA receptor is a type of glutamate receptor that is involved in learning, memory, and synaptic plasticity. By blocking the NMDA receptor, memantine is thought to reduce the excessive stimulation of neurons that can occur in Alzheimer's disease. Memantine was first synthesized in the 1960s by researchers at the pharmaceutical company Boehringer Ingelheim. It was originally investigated as a potential treatment for epilepsy, but it was found to be more effective in treating Alzheimer's disease. Memantine is typically taken orally, and it is generally well-tolerated. The most common side effects are dizziness, headache, and constipation. Memantine is not a cure for Alzheimer's disease, but it can help to improve cognitive function and slow the progression of the disease. Research into the mechanism of action of memantine is ongoing, and there is a great deal of interest in developing new drugs that target the NMDA receptor. Memantine is a valuable tool for treating Alzheimer's disease, and it is likely to continue to be used for many years to come.'

Effects

Memantine has a small beneficial effect at six months in moderate to severe AD. Memantine has an adjunctive effect on neurosyphilis-related neuropsychiatric disorder via modulation of the glutamatergic neurotransmission and microglia-induced neuroinflammation.

Memantine has shown clinical benefits in the key domains of AD, both as monotherapy and in combination with a cholinesterase inhibitor (ChEI). Memantine has an acceptable safety and tolerability in patients with OCD and might have a positive effect on their executive function.

Roles (5)

RoleDescription
dopaminergic agentA drug used for its effects on dopamine receptors, on the life cycle of dopamine, or on the survival of dopaminergic neurons.
antiparkinson drugA drug used in the treatment of Parkinson's disease.
NMDA receptor antagonistAny substance that inhibits the action of N-methyl-D-aspartate (NMDA) receptors. They tend to induce a state known as dissociative anesthesia, marked by catalepsy, amnesia, and analgesia, while side effects can include hallucinations, nightmares, and confusion. Due to their psychotomimetic effects, many NMDA receptor antagonists are used as recreational drugs.
neuroprotective agentAny compound that can be used for the treatment of neurodegenerative disorders.
antidepressantAntidepressants are mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions.

Caregiver Activity Survey Change From Baseline

The Caregiver Activity Survey (CAS) was developed to measure the time caregivers spend aiding Alzheimer patients with their day-to-day activities. The CAS consists of six items that ask for an estimate in hours and minutes of the time that the caregiver spent during the previous 24 hours performing these particular activities. The six CAS items are as follows: 1) communication with the person, 2) using transportation, 3) dressing, 4) eating, 5) looking after one's appearance, and 6) supervising the person. The more caregiving hours the worse the patient's functioning level. Outcome analysis is average least square means change from baseline. (NCT00235716)

The Neuropsychiatric Inventory (NPI) assesses psychological and behavioral problems in patients with dementia. For each of twelve domains, there are four scores: frequency, severity, total frequency x severity, and caregiver distress. The frequency x severity total scores from each domain are summed for an overall total score that ranges from 0 to 144. The total caregiver distress scores are also summed for an overall total caregiver distress score that ranges from 0 to 60. The secondary endpoint for the trial will be the overall frequency times severity total score. Outcome analysis is average least square means change from baseline. (NCT00235716)

Modified Quick Inventory of Depressive Symptoms Self Report Scale (QIDS-SR)

The 16 item Quick Inventory of Depressive Symptomatology (QIDS-SR16) (Rush et al. 2003) is designed to assess the severity of depressive symptoms, with higher scores representing more severe forms of depression. When complete, the QIDS are scored by summing responses to obtain a total score ranging from 0 to 27. Either appetite increase or decrease, but not both, are used to calculate the total score. Weight increase or decrease, but not both, are used to calculate the total score. Scores 0-5 indicate no severity of depression; 6-10 is mild; 11-15 is moderate; 16-20 is severe; 21-27 is very severe levels of depression. Participants were evaluated at baseline and at weeks 1, 2, 3, 4, 6 & 8. (NCT00344682)

Improvements From Baseline Scores After 6 and 12 Weeks of Memantine Compared to Placebo on the Trail Making Test Part B.

Trail Making Test Part B consists of 24 circles on a piece of paper, but rather than all of the circles containing numbers, half of the circles have the numbers 1-12 in them and the other half (12) contain the letters A-L. The person taking the test has the more difficult task of drawing a line from one circle to the next in ascending order; however, he must alternate the circles with numbers in them (1-13) with circles with letters in them (A-L). In other words, he is to connect the circles in order like this: 1-A-2-B-3-C-4-D-5-E and so on. Lower scores are better scores and the range of scores can be from 0 to no limit for Trail Making Test part B. This is a timed test and the number of seconds to complete the task is recorded.

On the record form, there are a series of rows containing geometric figures in the top half, but the bottom half is left blank. When it is clear that the subject understands the task, he or she is told to fill in the remaining boxes as quickly as possible, completing one box at a time, one row at a time, before proceeding to the next. Skipping from box to box with the same geometric figure is not permitted. Subjects receive one point for each correctly completed box. The total score is the total number of correctly completed boxes in the time allowed. The practice items are not counted in the scoring. The test can be administered by having the subject write out the correct response or by having the subject report the correct answer (i.e., number) aloud. Higher scores are better scores and the range of scores can be from 0 to 110 for SDMT oral scores. (NCT00462228)

Fuld Object Memory Evaluation

"Ten common objects in a bag were presented to determine whether the subject could identify objects by touch. The subject was not told that memory of this event would be tested. The subject names each object and then pulls it out of the bag to see if he is correct. After distracting the subject, by asking the patient to say words rapidly from a single category (rapid verbal retrieval), the subject is asked to recall the objects from the bag. The subject was then offered two more chances to learn and recall them (store and retrieve) by reminding the subject of omitted items after each recall, with rapid verbal retrieval preventing rehearsal before each recall opportunity.~Retrieval scores were summed over the three trials with the range of possible scores being 0-30.

Median Time to Neurocognitive Failure

Neurocognitive failure is defined as the first cognitive failure on any of the neurocognitive tests: the HVLT-R for immediate recall, delayed recognition, and delayed recall; the Controlled Oral Word Association Test (COWAT); the Trail-Making Test (TMT) Parts A and B. Cognitive failure for each test is defined as a post-treatment score that meets one of the following criteria: follow-up score is at least 2 standard deviations worse than the patient's personal baseline score or the patient's raw score change is greater than the reliable change index. The cumulative incidence approach was used to estimate the median time to neurocognitive failure to account for the competing risks of disease progression and death. (NCT00566852)

Change in Functional Assessment of Cancer Therapy With Brain Subscale (FACT-Br) at 24 Weeks

The FACT-Br is a 50-question self-report questionnaire contains the following domains (scales): Physical well-being (7 questions), social/family well-being (7 questions), emotional well-being (6 questions), functional well-being (7 questions) and brain cancer subscale which contains concerns relevant to patients with brain tumors (23 questions). Each question has a value 0-4. For some questions a higher indicates better outcome and others are the opposite. The former are summed as is, the latter are reversed in value before adding, such that each domain ranges from 0 to 4 times the number of questions in the domain, with 0 indicating worst and the highest possible value indicating best outcome. The FACT-Br total is obtained by adding all domains together if the overall question response rate is greater than 80%. Total scores on the FACT-Br range from 0 to 184 with lower scores indicating declining quality of life. Change is calculated as baseline score subtracted from 24-week score. (NCT00566852)

Yale Brown Obsessive Compulsive Scale Modified for Pathological Gambling (PG-YBOCS)

The PGYBOCS is a reliable & valid, 10-item, clinician administered scale that rates gambling symptoms within the last 7 days. The first 5 questions assess urges and thoughts associated with pathological gambling, and the last 5 questions assess the behavioral component of the disorder. Scores of 0 through 4 are assigned each item according to the severity of the response (0 = least severe response or none, 4 = most severe response or extreme)with a score ranging from 0-40. Each set of questions (1-5 and 6-10) can be totaled separately for the component score (urges/thoughts and behavioral) as well as together for a total score. A score of 0 indicates no problems while increasing scores indicate increasing severity of problems with gambling. PG-YBOCS is used to measure changes across time. A decreasing score indicates a possible positive response to the intervention. Total score at baseline was compared with the study end to determine if the intervention was efficacious. (NCT00585169)

The patient is instructed to walk 25 feet as quickly as possible, but safely.~Paced Auditory Serial Addition Test-3 seconds (PASAT-3) is a measure of cognitive function that assesses auditory information processing speed and flexibility, as well as calculation ability.~The MSFC is based on the concept that scores for these 3 dimensions-arm, leg, and cognitive function are combined to create a single score that can be used to detect change over time in a group of MS patients. This is done by creating Z-scores for each component of the MSFC. Implicit in this approach is the idea that patients who deteriorate or improve on all 3 component measures will have an overall larger change than patients who change on only 1 of the 3 measures. The MSFC score was transformed to z-scores, with higher scores indicating better outcome." (NCT00638027)

By spasticity we mean muscle stiffness and spasms.The MSSS-88 is a reliable and valid, patient-based, interval-level measure of the impact of spasticity in multiple sclerosis. Scores were summed, without weighting or standardization, to generate ordinal-level total scores just as any other Likert-type scale. Missing responses to items can be replaced with the mean score of the items completed (person-specific item mean score) provided that 50% or more of the items in a scale have been completed. The range is 8-32 and higher scores mean poorer outcome." (NCT00638027)

N-acetylaspartate

The change in N-acetylaspartate (NAA) measured with magnetic resonance spectroscopy (MRS) is the primary outcome measure. NAA is a metabolite found predominately in neuronal cells, and its amount indicates tissue well being (the higher the better). In MRS studies NAA (and other metabolites like choline or myoinositol) are presented as a ratio to creatine (Cr) also measured by MRS. The concentration of creatine does not change is used as an internal standard. The ratio NAA/Cr is unitless. In summary, the measurable outcome will be the NAA/Cr ratio change from pre-to post treatment. (NCT00933608)

The Change Scores in Memory Measures From Baseline to Post-treatment/Placebo Will be Compared Between the Memantine Treatment and Placebo Groups.

Change scores from pre- to post-treatment/placebo were calculated for the primary outcome measures, the Selective Reminding Test Continuous Long-Term Retrieval (range 0-72; higher scores indicate better memory) and 7-24 Spatial Recall Test Total Learning (range 0-35; total correct across 5 learning trials are summed, with higher scores indicating better memory) scores. These measures are scores on a scale, rather than representing standard units. (NCT01054599)

A Secondary Analysis Will Examine the Possible Sustained Benefit of Continued Memantine Use.

SRT-CLTR (range 0-72; higher scores indicate better memory), and 7-24 Spatial Memory Test (range 0-35; scores are summed across the 5 learning trials, with higher scores indicating better memory) scores will be assessed across the first (baseline) and third (post-open label memantine) testing sessions. These measures are considered to be scores on a scale, rather than standard units. The hypothesis was that subjects randomized to memantine would demonstrate sustained improvement from baseline, while the placebo group would demonstrate improvements after taking open label memantine (compared to baseline).

Prepulse Inhibition

"Prepulse inhibition of the startle reflex is the automatic reduction in startle magnitude (assessed here by EMG of orbicularis oculi) when a startling stimulus (here a 40 ms 118 dB(A) noise burst; PULSE) is preceded (here 10 - 120 msec) by a weak stimulus (here a 20 msec burst 16 dB over background PREPULSE). A %PPI metric is calculated based on the relative startle magnitude on (PREPULSE + PULSE) trials vs. PULSE alone trials. Possible maximal inhibition is 100%; there is no maximal negative value of inhibition. There is no clear advantage or disadvantage for lower or higher %PPI values, though on average, schizophrenia patients demonstrate lower % values compared to matched healthy subjects." (NCT01555697)

The Social Responsiveness Scale (SRS) is a 65-item informant-rated assessment with total raw score ranging from 0 (no impairment) to 195 (severe social impairment). Each item is associated with 1 of 5 subscales (social awareness, social cognition, social communication, social motivation and autistic mannerisms). Each item is rated on a 4-point scale from 1 (not true) to 4 (almost always true). The scores are then transposed to a scale from 0 to 3 and scores are summed within each of the 5 subscales. A higher score indicates greater severity of social impairment. (NCT01592747)

Behavior Rating Inventory of Executive Function (BRIEF) Inhibit

The Behavior Rating Inventory of Executive Function (BRIEF) Inhibit subscale is a rating scale completed by the participant and independently by an observer that assesses the ability to control impulses (inhibitory control) and to stop engaging in a behavior. The frequency of behaviors indicated by items is rated on a 3-point scale (never, sometimes, often). The raw score for the Inhibit subscale is the sum of ratings for the 8 items included in this measure. This sum was converted to a T-score (mean=50; SD=10) for analysis. Higher scores suggest a higher level of dysfunction in a specific domain of executive functions. (NCT02240589)

Adaptive/Behavioral Functioning of the Participants as Assessed by Change in Score on the Scales of Independent Behavior-Revised (SIB-R)

This is a measure of adaptive functioning that integrates information from 13 different domains (e.g., gross motor, social interaction, eating, toileting, dressing, personal self-care, etc.). It is in a questionnaire format, which a caregiver can complete while the participant is being tested. Standard scores for all indices will be derived from age norms that extend from birth to age 80, as these were used as dependent variables. We report here on the Broad Independence Score recorded as change in score from baseline (T1) to after the treatment (T2). The minimum value of the SIB-R Score Scale in this study was -24 (this number is below 0 because -24 was the minimum value for the worst performing participant in the trial) and the maximum value of this scale is 153; higher scores mean better outcomes.

The minimum value of the speed of response of execution to Go targets is 280 milliseconds (ms) and the maximum value is 1000 ms; higher scores mean worse outcomes. The values for this measure have been recorded as change in score from baseline (T1) to after the treatment (T2)." (NCT02304302)

Intellectual Functioning of the Participants as Assessed by Change in Score on the Matrices Subtest of the Differential Ability Scales-II (DAS-II)

This test provides a measure of non-verbal reasoning ability that requires subjects to visually inspect a matrix of 4 or 9 pictures that has a missing piece. Participants have to infer a rule or pattern in the stimuli and select the appropriate response from a range of 4-6 possibilities. Since age norms are not available for individuals older than 17y11m, the ability score will be used as the dependent variable. This is an intermediate score based on Rasch modeling that corrects for different items set being administered to participants. The minimum value of the DAS-II Rasch Score Scale is 0 and the maximum value is 153; higher scores mean better outcomes. The values for this measure have been recorded as change in score from baseline (T1) to after the treatment (T2). (NCT02304302)

Efficacy of the Drug Memantine as Assessed by Change in Score on the California Verbal Learning Test-II (CVLT-II) Short Form Total Free Recall

The primary efficacy measure is focused on episodic memory. The CVLT-II short form assesses supraspan word learning ability as an index of episodic verbal long-term memory. We hypothesize that treatment with memantine will produce significant improvements in this test. The main dependent variable selected, based on prior literature was the total number of target items correct summed across learning trials 1-4. The values for this measure have been recorded as change in score from baseline (T1) to after the treatment (T2). Scale Range: from 0 to 36; higher scores represent better outcomes. (NCT02304302)

Linguistic Functioning of the Participants as Assessed by Change in Score on the Test for Reception of Grammar 2nd Edition (TROG-II)

This is a measure of receptive syntax skills (Bishop, 1983). Participants are asked to point to a picture (out of 4) that corresponds to a phrase or sentence spoken by the examiner. The total number of items correct (rather than blocks passed) will be used as the dependent variable, following the administration manual's ceiling rule. The values for this measure have been recorded as change in score from baseline (T1) to after the treatment (T2). The minimum value of the scores is 0 and the maximum value is 40; with higher scores considered to be a better outcome. (NCT02304302)

Safety and Tolerability of the Drug Memantine as Assessed by Change in QTc Interval

Incidence of adverse events was monitored by clinical history, physical examinations, electrocardiograms (ECGs), clinical laboratory tests, the Screen for Childhood Anxiety Related Emotional Disorders (SCARED). Here, we report the analysis of the effect of memantine treatment on QTc intervals because of its clinical importance for this analysis for potential drug toxicity. QTc intervals ≥ 450 ms are generally considered long, and drug-induced QTc interval prolongations ≥ 60 ms are generally considered clinically relevant. (NCT02304302)

Time to Neurocognitive Failure

Neurocognitive failure is defined as the first failure, defined as a neurocognitive decline using the reliable change index (RCI) on at least one of the following assessments or parts of : Hopkins Verbal Learning Test - Revised (HVLT-R), Trail Making Test (TMT), or Controlled Oral Word Association (COWA). The HVLT-R has 3 parts that were analyzed separately for decline: Total Recall, Delayed Recall, and Delayed Recognition. The TMT has 2 parts that were analyzed separately: Part A and Part B. Neurocognitive failure rate is estimated using the cumulative incidence method. Analysis was planned to occur after 233 events were reported. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Six-month rates are provided.Analysis was planned to occur after 233 events were reported. (NCT02360215)

Change From Baseline in the Hopkins Verbal Learning Test -Revised (HVLT-R) Delayed Recall Score (Neurocognitive Decline)

The HVLT-R assesses verbal learning and memory. The test involves memorizing a list of 12 nouns for 3 consecutive trials (Total Recall), recalling the 12 targets after a 20-minute delay (Delayed Recall), and then identifying the 12 targets from a list of semantically related or unrelated items (delayed recognition). Raw scores are derived for total recall (sum of the number of targets correctly recalled), delayed recall (sum of the number of targets correctly recalled), and a delayed recognition discrimination index (sum of targets incorrectly identified subtracted from the sum of the number of targets correctly identified). The range of scores for total recall is 0 to 36, for delayed recall is 0 to 12, and -12 to 12 for recognition. A higher score indicates better functioning. Scores are standardized, adjusting for age, education, and gender as necessary, such that mean 0 and standard deviation is 1.

The TMT is a neuropsychological test of visual attention and task switching that can provide information about visual search speed, scanning, speed of processing, mental flexibility, and executive functioning. Subject is instructed to connect a set of 25 dots as quickly as possible while still maintaining accuracy. There are two parts to the test: in the first (Part A), the targets are all numbers (1, 2, 3, etc.) and the test taker needs to connect them in sequential order; in the second part (Part B), the subject alternates between numbers and letters (1, A, 2, B, etc.). The score is the amount of time, in seconds, that it takes the patient to complete each maze. The range for Part A is 0 to 180 (3 minutes) and for Part B is 0 to 300 (5 minutes). Lower scores indicate better functioning. Scores are standardized, adjusting for age, education, gender as needed, so that mean is 0 and standard deviation is 1.

Investigation of Neurological Deficit by National Institute of Health Scale Score (NIHSS)

The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher score is indicative of some level of impairment in neurological function. (NCT02535611)

Investigation of Neurological Deficit by National Institute of Health Scale Score (NIHSS)

The National Institutes of Health Stroke Scale, or NIH Stroke Scale (NIHSS) is a tool used by healthcare providers to objectively quantify the impairment caused by a stroke. The NIHSS is composed of 11 items, each of which scores a specific ability between a 0 and 4. For each item, a score of 0 typically indicates normal function in that specific ability, while a higher score is indicative of some level of impairment. The individual scores from each item are summed in order to calculate a patient's total NIHSS score. The maximum possible score is 42, with the minimum score being a 0. Higher score is indicative of some level of impairment in neurological function. (NCT02535611)

ADCS - CGIC Score at Week 12

The Alzheimer's Disease Cooperative Study - Clinical Global Impression of Change (ADCS-CGIC) is a semi-structured interview designed to assess clinically relevant changes in patients with Alzheimer's disease. Items in the ADCS-CGIC interview provide general information, and information about cognition, behaviour, social and daily functioning. Responses to ADCS-CGIC interview result in a global clinical judgement of severity (at baseline) and clinically relevant change at subsequent visits. Severity rated at baseline is only used for reference. The severity at baseline is rated on a 7-point Likert-type scale from 1(normal, not ill at all) to 7 (among the most extremely ill patients). The ADCS-CGIC relevant change is rated on a 7-point Likert-type scale from 1 (marked improvement) to 7 (marked worsening). (NCT02553928)

Mismatch Negativity (MMN); Unit of Measure of MMN is Microvolts.

85 dB SPL stimuli were presented via Etymotic ER3-A insert earphones. A 4-tone auditory oddball paradigm with 82% standards & 18% deviant stimuli, differed from standard in pitch, duration, or both. A pseudorandomized sequence produced a minimum of 3 standard tones between each deviant stimulus. All tones had 5-ms rise/fall times presented with a fixed 500-ms stimulus onset asynchrony. Subjects viewed a silent movie & instructed to ignore auditory stimuli. EEG were continuously recorded at a sampling rate of 2048-Hz from 64 channels, using BioSemi ActiveTwo system & downsampled to 512-Hz. Deviant-minus-standard difference waves were generated for each deviant type & low-pass filtered (20-Hz zerophase shift, 24 dB/octave rolloff). MMN was computed as mean amplitude across 135-205 ms range for each deviant type in difference waveforms at electrode Fz. Data were analyzed by RM-ANOVA, with diagnosis as a between-subject factor, & drug condition (placebo vs MEM) as a within-subject factor. (NCT03860597)

Prepulse Inhibition (PPI)

"PPI of the startle reflex is the automatic reduction in startle magnitude (assessed by EMG of orbicularis oculi) when a startling stimulus (40 ms 118 dB(A) noise burst; PULSE) is preceded (10-120 msec) by a weak stimulus (here a 20 msec burst 16 dB over background PREPULSE). A %PPI metric is calculated based on the relative startle magnitude on (PREPULSE + PULSE) trials vs. PULSE alone trials. Possible maximal inhibition is 100%; there is no maximal negative value of inhibition. There is no clear advantage or disadvantage for lower or higher %PPI values, though on average, schizophrenia patients demonstrate lower % values compared to matched healthy subjects. Day 1 was baseline testing: testing occurred, data was collected, but no intervention was given. There were two possible interventions: active (MEM 20 mg po) and placebo. One intervention was given on day 7 post baseline, the other intervention was given on day 14 post baseline, with order of intervention balanced." (NCT03860597)

"Gamma Auditory Steady-state Response (ASSR). The Primary Unit of Measure of Auditory Steady State Response (ASSR) is Gamma Evoked Power (γEP), Expressed as Microvolts-squared."

1 ms, 85 dB clicks were presented in 500 ms trains at a frequency of 40 Hz; 250 click trains were played (inter-train interval=0.5 s). EEG was continuously recorded with 64-channel BioSemi ActiveTwo system (sampling rate=2048 Hz). Data processed offline via Matlab, EEGlab, & BrainVision Analyzer. Continuous data were segmented relative to stimulus onset (-100 ms to 500 ms) & each epoch was baseline-corrected relative to 100 ms pre-stimulus interval. γEP was assessed based on first 100 artifact-free epochs at Fz. Averaged epochs across click trains were transformed into power spectrum via fast Fourier transform using a bin width of 2 Hz. 40 Hz power spectrum was averaged across 4 Hz band from 38-42 Hz. Data were analyzed by RM-ANOVA, with diagnosis as a between- & drug condition (placebo vs MEM) as a within-subject factor. Analyses revealed robust & time bin-independent effects of diagnosis & drug across 200-500 ms window & thus this interval was the focus of all subsequent analyses. (NCT03860597)

Change in Processing Speed and Executive Function - Trail Making Test

The Trail Making Test (TMT) is an objective measure of processing speed (part A) and executive function (part B). In part A, the participant is given a diagram of 25 circles, labeled 1 - 25, and asked to connect the circles in ascending order. In part B, the diagram of 25 circles includes some with numbers (1-13) and some with letters (A-L), and the participant is asked to connect the circles alternating between numbers and letters. Performance is measured in the number of seconds required to complete each task (lower is better). (NCT04033419)

The Migraine Disability Assessment MIDAS Scale Will Measure Before and After the Treatment to Improve the Quality of Life in Both Groups After Three Months of Treatment.

"To compare the average of Memantine against the group that receives Valproate before and after starting preventive treatment. Using the Migraine Disability Assessment scale (The score is the sum of days missed from work or school, days of housework missed, days of missed non-work activities, and days of work or school plus days of housework in which productivity in the last three months) to compare punctuation changes. The MIDAS score is divided into four degrees, the minimum score is 0 points, and the maximum score is 70. A higher value represents a higher difficulty to carry out a satisfactory lifestyle, and a score higher than 20 points already represents a high limitation to enjoying daily activities:~Grade I (0-5 points): Slight limitations and few patient treatment needs. Grade II (6-10 points): Moderate limitations and treatment needs. Grade III (11-20 points) and IV (21 or more points): Severe and significant punctuation treatment needs." (NCT04698525)

Massachusetts General Hospital Hairpulling (Skin Picking) Scale

Brief, self-report scale for assessing repetitive hairpulling (or skin picking). Because of a lack of an identical scale for skin-picking behavior, this scale was modified for skin picking for individuals with SPD to keep the outcome measure consistent across disorders. Seven individual items, rated for severity from 0 to 4, assess urges to pull (pick), actual pulling (picking), perceived control, and associated distress (range 0-28). The change in scores from baseline to after 8 weeks is reported. Negative values indicate a decrease in score from baseline to 8 weeks, while positive values indicate an increase in score from baseline to 8 weeks. (NCT04792645)
