A common idiom of distress among Latinos in the United States and Latin America. A number of other ethnic groups have related, though often somewhat distinctive, ideas of “nerves” (such as nevra among Greeks and nervi among Italians). Nervios refers both to a general state of vulnerability to stressful life experiences and to a syndrome brought on by difficult life circumstances. Symptoms include emotional distress, irritability, sleep disturbances, inability to concentrate, and mareos (dizziness with occasional vertigo-like manifestations). It is a very broad syndrome that ranges from cases free of a mental disorder to presentations resembling adjustment, anxiety, depressive, dissociative, somatoform, or psychotic disorders.
