dipyridamole and Dementia Praecox

dipyridamole has been researched along with Dementia Praecox in 5 studies

Dipyridamole: A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Dipyridamole also potentiates the antiaggregating action of prostacyclin. (From AMA Drug Evaluations Annual, 1994, p752)
dipyridamole : A pyrimidopyrimidine that is 2,2',2'',2'''-(pyrimido[5,4-d]pyrimidine-2,6-diyldinitrilo)tetraethanol substituted by piperidin-1-yl groups at positions 4 and 8 respectively. A vasodilator agent, it inhibits the formation of blood clots.

Trial Outcomes

Change in Negative Symptoms by Treatment Assignment

The Scale for the Assessment of Negative Symptoms (SANS) total score, minus the global items, inappropriate affect, poverty of content of speech, and attention items, used to measure negative symptoms. Mean SANS total score by treatment and week. SANS total score range = 0-85. Higher scores indicate more severe negative symptoms. (NCT00349973)

Change in Positive Symptoms by Treatment Assignment

"The Brief Psychiatric Rating Scale (BPRS) consists of 20 items, with 6 of these items used to assess positive symptom change. The BPRS positive symptom items are: somatic concern, conceptual disorganization, hostility, suspiciousness, hallucinatory behavior, and unusual thought content. Each scale ranges from 1=Not Present to 7=Very Severe. A higher score indicates a more severe positive symptom rating." (NCT00349973)

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS)

The RBANS is a brief, individually administered test designed to evaluate neuropsychological status of adults, ages 20-89. The 12 subtests measure attention, language, visuospatial/constructional abilities, and immediate and delayed memory. The raw scores from the subtests are scaled together to create index scores, and these are summed for conversion to a total scale score. Higher score equals a better outcome. The total index score range for the RBANS is 40-160. (NCT00349973)
