amantadine and Brain Injury, Chronic

amantadine has been researched along with Brain Injury, Chronic in 3 studies

amant: an antiviral compound consisting of an adamantane derivative chemically linked to a water-solube polyanioic matrix; structure in first source

Brain Injury, Chronic: Conditions characterized by persistent brain damage or dysfunction as sequelae of cranial trauma. This disorder may result from DIFFUSE AXONAL INJURY; INTRACRANIAL HEMORRHAGES; BRAIN EDEMA; and other conditions. Clinical features may include DEMENTIA; focal neurologic deficits; PERSISTENT VEGETATIVE STATE; AKINETIC MUTISM; or COMA.

Trial Outcomes

Change in Neuropsychiatric Inventory - Irritability Domain Assessed by Observer Day 28

The Neuropsychiatric Inventory (NPI) is a 40-item rating scale developed to assess 12 behavioral domains. Only the NPI-Irritability (NPI-I) domain was used for this study. NPI-I measures irritability with items including: bad temper, rapid mood changes, sudden anger, impatience, crankiness, argumentative. The rater selects the frequency (1-3) and severity (1-4) of the most problematic of these behavioral aspect(s) over the preceding month. The NPI score is the product of the frequency and severity for the NPI most problematic item score. The primary outcome measure was the proportion of participants with greater than two-point increase on the Neuropsychiatric Inventory Irritability domain. The total range is 1 (least irritability) - 12 (worst irritability). (NCT00779324)

Clinical Global Impressions Day 28

Study physician's impression of change since study onset. Clinicians Global Impressions of Change (CGI) is a sensitive, standardized tool to assess psychopharmacologic treatment response completed by the study physician. The Global Improvement (GI) CGI subscale documented the clinician's impression of change. The GI uses a 7-point scale to assess beneficial and negative effects. Low GI values (1 -3) indicate improvement; higher values (4-7) represent worsening. (NCT00779324)
