Understanding Schizophrenia and Depression Medication

Dopamine plays a crucial role in executive functions, motivation, and movement control.
Schizophrenics have increased dopamine in the nucleus accumbens and decreased dopamine in the prefrontal cortex.
Increased dopamine in the nucleus accumbens leads to positive symptoms in schizophrenia, while decreased dopamine in the prefrontal cortex causes negative and cognitive symptoms.
Antipsychotics primarily target increased dopamine in the nucleus accumbens and are ineffective for negative and cognitive symptoms.
First generation antipsychotics target mesolimbic dopamine, while second generation antipsychotics are more selective for D2 receptors.
Chronic use of antipsychotics can result in irreversible movement disorders.
Blocking D1 and D2 receptors can disrupt normal movement, and the nigrostriatal dopamine pathway is important for non-voluntary movement.
First generation antipsychotics inhibit this pathway, leading to Parkinson's-like symptoms and involuntary movements.
Second generation antipsychotics are more selective for D2 receptors, resulting in fewer extra parameter side effects.
Antipsychotics that target D2 receptors are effective for reducing positive symptoms but do not help with negative and cognitive symptoms.
First generation antipsychotics have cardiotoxicity and extra parameter side effects, while second generation antipsychotics have fewer extra parameter side effects but can still cause tardive dyskinesia.
Decreased reward pathway dopamine interferes with reward processing and movement, and enhanced dopamine neurotransmitters at D2 receptors produce positive symptoms of schizophrenia.
