Does DGAVP influence memory, attention and mood in young healthy men?
Psychopharmacology
|January 1, 1987
Summary
This study found that desglycinamide-arginine-vasopressin (DGAVP) did not improve memory or alertness in healthy males. However, DGAVP significantly enhanced mood and concentration levels.
Area of Science:
- Neuroscience
- Pharmacology
- Psychology
Background:
- The vasopressin theory suggests vasopressin peptides may enhance memory.
- Desglycinamide-arginine-vasopressin (DGAVP) is a vasopressin analog with potential cognitive effects.
Purpose of the Study:
- To investigate the influence of increasing doses of DGAVP on memory in healthy male volunteers.
- To evaluate the effects of DGAVP on mood, alertness, and sleepiness.
Main Methods:
- Double-blind, placebo-controlled design.
- Intranasal administration of DGAVP with daily increasing doses (0.1 mg to 10.0 mg) over five days.
- Assessment of memory, mood, alertness, and sleepiness in two groups of ten healthy male volunteers.
Main Results:
- DGAVP did not significantly affect memory or alertness.
- A significant increase in concentration level and mood was observed with DGAVP administration.
- No significant effects on sleepiness were reported.
Conclusions:
- The study provides no support for the vasopressin theory of memory improvement.
- DGAVP appears to modulate attention and improve mood rather than enhance memory.
- Further research into the attention-modulating effects of DGAVP is warranted.
