Cocaine-induced mood disorder — Clinical Guidelines

Overview

Cocaine-induced mood disorders encompass a spectrum of neuropsychiatric symptoms including mood disturbances, often secondary to cerebrovascular complications or direct neurotoxic effects of cocaine use. These conditions can manifest acutely and may require nuanced management beyond cessation of drug use.

Diagnosis

Clinical Presentation: Neurological deficits, mood changes, and psychiatric symptoms often occur within hours of cocaine use. 2 3

Imaging Studies: MRI and CT angiography (CTA) are crucial for identifying cerebrovascular events such as infarcts, hemorrhages, and vasospasm. 2 3

Laboratory Tests: ANCA serology may be considered, particularly in cases with midline destructive lesions, though its predictive value for disease severity remains unclear. 1

Perfusion Imaging: CT perfusion (CTP) aids in differentiating multifocal vasospasm-related ischemia from thromboembolic stroke. 2

Management

Immediate Stabilization: Focus on supportive care, including neurological monitoring and management of acute symptoms. 2 3

Avoid Thrombolytics: Exclude thrombolytic therapy in suspected vasospasm to prevent exacerbating ischemia. 2

Cessation Support: Provide counseling and pharmacotherapy (e.g., buprenorphine, naltrexone) to aid in cocaine cessation. 3

Psychiatric Intervention: Consider psychiatric evaluation and treatment for mood disorders, possibly including antidepressants or mood stabilizers. 3

Special Populations

Comorbidities: Patients with other stroke risk factors may require tailored management strategies, though specific guidelines are limited. 3

No Specific Data on Pregnancy, Pediatrics, or Elderly: The abstracts do not provide detailed insights into these populations. 1 2 3

Key Recommendations

Utilize imaging modalities such as MRI, CTA, and CTP to accurately diagnose cerebrovascular complications in cocaine users. (Evidence: Moderate) 2 3

Avoid thrombolytic therapy in suspected cases of cocaine-induced multifocal vasospasm to prevent worsening ischemia. (Evidence: Weak) 2

Integrate psychiatric support alongside neurological care to address mood disorders arising from cocaine use. (Evidence: Expert opinion) 3
