Psychedelics like psilocybin and LSD, acting through 5-HT2A receptors, rapidly and lastingly improve depression and anxiety by modulating neuroplasticity and brain connectivity. They may also help with addictions, post-traumatic stress, and obsessive-compulsive disorder. This article explores their potential in Parkinson's disease, both for treating depression, anxiety, and impulse control disorders and for neuroprotection. Psychedelics stimulate synaptogenesis, increase brain-derived neurotrophic factor, and have anti-inflammatory effects. However, clinical trials are needed to confirm safety and efficacy in Parkinson's disease.
