Cognitive dysfunction in depression.

Cognitive Dysfunction' was assessed in 30patients diagnosed to have Major Depression (DSM III R), using the PCI memory scale and the Wechsler Adult Performance Intelligence Scale, form PR both of which have been developed and standardised in India. Depressed patients revealed marked impairment on tests of attention and concentration, and immediate and delayed recall on tests of memory (PCI); while tests of performance (WAPIS) revealed global impairment. This impairment reversed with recovery from depression. While improved test scores occured along with improvement in depression, there was no direct correlation between the two i.e. the degree of improvement in WAPIS/PGI total scores was not directly proportional to the degree of improvement in depression scores.
