Ketasyn In Age-Associated Memory Impairment
The purpose of this study is to determine whether Ketasyn, a compound that increases energy availability in the brain, improves memory in older adults with "normal" loss of memory abilities since early adult life.
One physiological hallmark of aging in mammals is a decreased uptake and metabolism of glucose within the brain. The impaired glucose metabolism in the brain may contribute or exacerbate the cognitive deficits observed during normal aging. Facilitation of memory in elderly individuals occurs when glucose levels are elevated by the administration of carbohydrate. However, such a treatment poses challenges since elevated blood glucose levels are difficult to maintain and must be within a relatively narrow window, as excessive hyperglycemia is associated with cognitive impairments. The purpose of this study is to explore whether increasing levels of other substrates for the brain improves cognitive functioning in normal aged individuals with memory disorders.
Study participants will be 120 men and women aged 50-85 who have been diagnosed as having Age-Associated Memory Impairment (AAMI). During the double-blind period of the protocol, 60 participants will receive Ketasyn™, and 60 participants will receive a matching placebo. Ketasyn™ or the matching placebo will be administered once a day for ninety days by mixing powder in 8 ounces of a liquid. Each participant will be seen six (6) times: at Screening; Baseline; treatment days Days 30, 60, 90; and 14 days after the conclusion of treatment (Day 104).

Primary Progressive Nonfluent Aphasia
A form of frontotemporal lobar degeneration and a progressive form of dementia characterized by motor speech impairment and AGRAMMATISM, with relative sparing of single word comprehension and semantic memory.
Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
Temporary storage of information for a few seconds to hours, as opposed to long-term memory which refers to material stored for days, years, or a lifetime.
Disturbances in registering an impression, in the retention of an acquired impression, or in the recall of an impression. Memory impairments are associated with DEMENTIA; CRANIOCEREBRAL TRAUMA; ENCEPHALITIS; ALCOHOLISM (see also ALCOHOL AMNESTIC DISORDER); SCHIZOPHRENIA; and other conditions.
A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
