Dehydroepiandrosterone sulfate, a neuroactive neurosteroid, plays a major role in brain development and aging by influencing the migration of neurons, arborization of dendrites, and formation of new synapses[1][2][3].

In Vitro	Dehydroepiandrosterone sulfate (DHEAS) selectively increased the length of neurites containing the dendritic marker MAP-2[1]. Dehydroepiandrosterone sulfate (DHEAS) has been reported to increase neuronal excitability (firing rate) when directly applied to septal-preoptic neurons[1]. Dehydroepiandrosterone (DHEA) is produced in prodigious quantities by the humanadrenal, principally as the 3-sulfoconjugate DHEA sulfate (DS) during intrauterine life[2]. Dehydroepiandrosterone sulfate (DHEAS) is generally nontoxic and lacks adverse side effects even when it is administered chronically[3].
In Vivo	DHEAS chronic administration produces a dose-dependent effect on performance[3]. Animal Model: Sixty-four male Sprague-Dawley rats, approximately 90 days of age (300-400 g)[3]. Dosage: 5, 10, or 20 mg/kg. Administration: Subcutaneous injection starting 7 days post-surgery and 1 h prior to all behavioral testing. Result: Significantly effective in improving latency to reach the platform as compared to injured rats receiving vehicle.
