Profound behavioral toxicity due to tricyclic antidepressants
The Journal of Nervous and Mental Disease
|October 1, 1986
Summary
Tricyclic antidepressant toxicity is common in the elderly but rare in young people. This case highlights significant behavioral side effects from imipramine and desipramine in a young woman, mimicking psychotic depression.
Area of Science:
- Pharmacology
- Neuroscience
- Psychiatry
Background:
- Tricyclic antidepressants (TCAs) are widely used for depression.
- Behavioral toxicity from TCAs is well-documented in elderly patients.
- Toxicity in younger populations is infrequently reported.
Observation:
- A young woman presented with severe behavioral disturbances.
- Her symptoms mimicked agitated psychotic depression.
- Elevated plasma levels of imipramine and desipramine were detected.
Findings:
- The patient experienced significant behavioral toxicity due to high TCA plasma levels.
- This presentation highlights a rare occurrence of TCA-induced toxicity in a young individual.
- The symptoms were initially misdiagnosed as a primary psychiatric disorder.
Implications:
- Clinicians should consider TCA toxicity in young patients presenting with unexplained behavioral changes.
- Monitoring TCA plasma levels may be crucial, even in younger patients, to prevent adverse effects.
- This case broadens the understanding of TCA toxicity beyond the elderly population.
