memantine has been researched along with Amnesia in 7 studies
Amnesia: Pathologic partial or complete loss of the ability to recall past experiences (AMNESIA, RETROGRADE) or to form new memories (AMNESIA, ANTEROGRADE). This condition may be of organic or psychologic origin. Organic forms of amnesia are usually associated with dysfunction of the DIENCEPHALON or HIPPOCAMPUS. (From Adams et al., Principles of Neurology, 6th ed, pp426-7)

Effects of Combined Memantine (Namenda) Plus Escitalopram (Lexapro) Treatment in Elderly Depressed Patients With Cognitive Impairment[NCT01876823] | Phase 2/Phase 3 | 60 participants (Actual) | Interventional | 2006-04-30 | Completed | ||

Change in 24-item Hamilton Rating Scale for Depression (HAMD) scores from baseline to Week 48: HAMD measures depression severity based on a series of 24 items items. The range of HAMD total score is 0-74; 0 indicates no depressive symptoms and a maximum HAMD score is a 74, where the greater the score indicates more significant psychopathology. In this study, moderate to severe depression is considered a HAMD-24 greater than 14. (NCT01876823)

Change in Selective Reminding Test-Delayed Recall scores from baseline to Week 48: SRT Delay is administered 15 minutes after the immediate recall portion. Patients are asked to remember as many of the words as they can from the 6 trials. Maximum raw score is a 12 for free recall. If a patient is unable to recall a word, they are given a chance to recognize it among three incorrect word choices. Maximum raw score for recognition is 12. The greater the score on the delayed recall portion, the better the patient does on the assessment. (NCT01876823)

Change in Selective Reminding Test-Total Immediate Recall (SRT-IR) scores from baseline to Week 48: Measures word recall (maximum 12 words per trial, across 6 trials). Maximum total recall score across 6 trials is 72; minimum recall is 0 across 6 trials. The higher the raw score, the better the patient did at recalling the target words. The unit of measure is the raw score, or the sum of the number of words recalled across all 6 trials. (NCT01876823)

Change in Trails A scores from baseline to Week 48: Measures attention and executive function. It asks patients to connect numbers from 1-25 in numerical order as fast as they can. Patients are timed; the longer it takes for the patient to connect the numbers, the worse their score. Unit of measure is in seconds. The amount of errors that the patient makes during trails is also recorded. (NCT01876823)

Change from baseline to Week 48 on Trails B: Measures attention and executive function. It asks patients to connect numbers and letters in numerical to alphabetical order from (1-13 and A-L) as fast as they can. Patients are timed; the longer it takes for the patient to connect the numbers and letters, the worse their score. Unit of measure is in seconds. The amount of errors that the patient makes during trails is also recorded. (NCT01876823)

Change in Wechsler Memory Scale-III scores from baseline to Week 48: The WMS-III Visual Reproduction sub-test was used to measure visual working memory and delayed memory. Patients were shown pictures of four drawings and were asked to reproduce them from memory immediately after seeing them, and 25 minutes after seeing them. The four scores are summed and the greater the total raw score, the better the patient did on the assessment. The maximum raw score for this test is a 41 on both the immediate and delayed portions (the overall range is 0-82 points). The change score is calculated using the total scores of both the immediate and delayed portions. (NCT01876823)

The CDR is a numeric rating scale that is used to quantify the severity of one's cognitive function. The scale goes from 0=normal; 0.5=mild cognitive impairment; 1 to 3=mild to moderate/severe dementia. CDR was used a dichotomous outcome measure (no=0; yes=1). (NCT01876823)

The CGI Cognitive Change follows a seven-point likert scale. Compared to the patient's condition at baseline in the study [prior to medication initiation], the patient's condition is rated as: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment. Responses from the entire group were calculated. Mean at final visit and baseline is reported below. (NCT01876823)

The CGI Depression Change follows a seven-point likert scale. Compared to the patient's condition at baseline in the study [prior to medication initiation], the patient's condition is rated as: 1=very much improved since the initiation of treatment; 2=much improved; 3=minimally improved; 4=no change from baseline (the initiation of treatment); 5=minimally worse; 6= much worse; 7=very much worse since the initiation of treatment. Responses were calculated for the entire group. Mean at final visit has been reported below. Higher mean at baseline indicates a decrease in depression scores. (NCT01876823)

"Somatic side effect rating scale which includes 26 common somatic side effects associated with previous medication clinical trials; rated by the study physician. Factors were dichotomized to yes or no responses on this scale, which equated to the symptom being either present or not present. Yes and no responses were given a value of 0 (no) or 1 (yes). Responses from the entire group were calculated and the mean at baseline and the last visit is reported below." (NCT01876823)
