Obsessive-compulsive disorder: cerebral calcium deficiency as a possible etiologic/pathogenetic factor--a case study

|February 18, 1998
Summary
Calcium channel blockers may worsen obsessive-compulsive disorder (OCD) symptoms by affecting neurotransmitter release. Alternative medications are recommended for OCD patients, especially those with cardiac conditions.
Area of Science:
- Neuroscience
- Psychiatry
- Pharmacology
Background:
- Obsessive-compulsive disorder (OCD) is a heterogeneous syndrome with suspected neurobiological underpinnings.
- Alterations in central nervous system (CNS) monoaminergic neurotransmitter systems are implicated in OCD pathobiology.
Observation:
- Calcium (Ca) concentration is crucial for regulating neurotransmitter release.
- Presynaptic Ca deficiencies can impair normal neurotransmission.
Findings:
- A case study revealed that increasing doses of a calcium channel blocker (CCB) significantly exacerbated OCD symptoms in a patient with comorbid cardiac pathology.
- Reducing and discontinuing the CCB led to marked amelioration of OCD symptomatology.
Implications:
- Minimal use of CCBs is suggested for individuals with OCD.
- Exploring alternative medications to CCBs for OCD treatment is warranted.
- The cerebral Ca deficiency hypothesis of OCD warrants further investigation in cardiology patient populations.
