Other Research
Common treatments for schizophrenia primarily target neurotransmitter systems, especially dopamine and serotonin. Antipsychotic medications work by blocking dopamine receptors to reduce psychotic symptoms like hallucinations and delusions, while atypical antipsychotics also affect serotonin receptors to help with mood and cognitive symptoms. Adaptogenic treatments such as Withania somnifera (Ashwagandha) are being explored for their potential to modulate neurotransmitter systems and reduce stress, which could benefit schizophrenia patients by addressing both core symptoms and stress-related issues.
