Board-certified psychiatrist Dr. Heywood W. Zeidman, MD brings more than 49 years of clinical practice to La Mesa Village from his Spring Street suite, affiliated with Psychiatric Centers at San Diego. A 1973 graduate of New York Medical College with residency training in psychiatry at UC San Diego Medical Center, Zeidman's practice handles complex psychopharmacological management, and his end-of-life psychiatric referrals include coordination with LakeView Hospice Home for palliative behavioral-health support. The practice's diagnostic scope covers ADHD, bipolar disorder, major depressive disorder, obsessive-compulsive disorder, PTSD, schizophrenia, eating disorders, and adolescent substance-use disorders. Medication-management protocols for movement-disorder side effects and treatment-resistant conditions require multidisciplinary coordination with rehabilitation providers including PRN Physical Therapy - La Mesa for tardive-dyskinesia motor assessment. Highest-acuity cases involve clozapine-management protocols for treatment-resistant schizophrenia, requiring mandatory absolute-neutrophil-count monitoring through the Clozapine REMS registry and titration schedules adjusted to metabolic and hematologic parameters.
