    Author: Baker IW, Jackson M, Bass C.
    Journal: Cogn Behav Neurol; 2005 Sep; 18(3):141-3. PubMed ID: 16175016.
    Abstract:
    OBJECTIVE: We describe a case of psychogenic malignant catatonia resulting in permanent cognitive impairment. BACKGROUND: Catatonia is a neuropsychiatric syndrome characterized by catalepsy, negativism, mutism, muscular rigidity, and mannerisms, often accompanied by autonomic instability and fever. Little is known about the long-term cognitive consequences of the syndrome. METHOD: Medical history includes neurologic examination, neuropsychological evaluation, electroencephalographic data, magnetic resonance imaging, sodium amytal interview, and treatment with electroconvulsive therapy. RESULTS: Selective deficits in executive function and an anterograde amnesia were evident a week post-ECT treatment and continued to be present at follow-up after 2 years and 8 months. CONCLUSION: The permanent cognitive impairments are considered in the context of catatonia as a frontal lobe syndrome.
