[Clinical features of asthenic conditions in young persons].

On the basis of examining 293 young patients (predominantly individuals with intelectual occupations) with asthenia the authors have established the clinical characteristics of asthenic states of various genesis. Psychogenic asthenias, asthenias in patients with a history of a craniocerebral injury and so-called adaptation asthenias are described in greater detail. The data obtained are important for the diagnosis, treatment and prophylaxis of the asthenic syndrome of variable genesis.
