Catastrophic reaction after cerebrovascular lesions: frequency, correlates, and validation of a scale.

The frequency and correlates of the catastrophic reaction (CR) were examined in 52 consecutive patients with an acute stroke lesion. A new scale proved reliable for measuring the severity of CR. The CR was significantly associated with depression, a personal and family history of psychiatric disorder, and subcortical lesions, which were mostly located in the basal ganglia. Patients with and without a CR, when matched for the presence and type of depression, differed only in that CR patients had significantly more anterior lesions and a significantly higher frequency of subcortical damage. Results demonstrate that the CR is significantly associated with poststroke depression and may be a specific manifestation of certain types of poststroke depression.
