Understanding Antipsychotics
Antipsychotics are medications that primarily work by affecting dopamine and other neurotransmitters in the brain. While originally developed for schizophrenia and psychosis, they're now widely used for various mental health conditions.

- ✓ Bipolar disorder (mania and depression)

- ✓ Tourette syndrome
- ✓ Severe insomnia
- ✓ PTSD
