First-generation antipsychotics, often referred to as typical antipsychotics, primarily target positive symptoms of schizophrenia. Positive symptoms include hallucinations, delusions, and disorganized thinking, which are often exaggerated behaviors or experiences that are not present in healthy individuals. These medications work primarily through dopamine receptor antagonism, particularly at the D2 receptor sites, which is effective in mitigating these types of symptoms.

In contrast, negative symptoms, which encompass a reduction or absence of normal emotional responses and behaviors (such as lack of motivation, emotional flatness, and social withdrawal), are less effectively targeted by these medications. First-generation antipsychotics do not significantly alleviate these symptoms because their mechanism of action does not adequately address the complex neurobiological underpinnings of negative symptoms. This distinction is crucial, as patients with schizophrenia often present with a combination of both positive and negative symptoms, and treatment approaches may need to be adjusted to address the latter more effectively, often requiring the use of second-generation antipsychotics or adjunctive therapies.

Behavioral symptoms encompass a broad range of actions that aren't necessarily confined to positive or negative categories, such as aggression or agitation, and cognitive symptoms refer to issues like impaired memory and executive function. While first-generation ant
