Introduction
In general, long-term alcohol consumption may lead to psychosis. Heavy and prolonged drinking is more likely to trigger psychiatric disorders, whereas moderate and long-term drinking may not cause such conditions. Moderate alcohol intake can be beneficial to physical and mental health, but chronic and excessive drinking may have adverse effects on the body. Therefore, it is recommended to adjust alcohol consumption according to individual health conditions in daily life.

Generally, long-term alcohol consumption may lead to psychosis. Heavy and prolonged drinking is highly likely to trigger psychiatric disorders; in contrast, moderate and long-term drinking may not cause psychosis.

1. Long-term heavy drinking: Chronic or excessive alcohol use can damage the central nervous system. Prolonged exposure of the brain to alcohol alters the balance of neurotransmitters, particularly dopamine and glutamate, leading to the emergence of psychiatric symptoms. This damage accumulates gradually and may manifest as mental confusion, illusions, hallucinations, delusions, and other symptoms.

2. Long-term moderate drinking: If daily alcohol intake is low, it typically does not cause significant damage to the central nervous system, so the risk of developing psychosis is relatively low.

In addition, maintaining a healthy lifestyle and good dietary habits while engaging in long-term moderate drinking can further reduce the likelihood of developing psychiatric disorders.

For patients who have already developed psychiatric symptoms, the primary step is to stop drinking. Psychological treatments such as cognitive behavioral therapy should be implemented, and if necessary, antipsychotic medications—such as olanzapine tablets, quetiapine fumarate tablets, or haloperidol tablets—may be used under medical supervision.

Moderate drinking may benefit physical and mental health, but long-term and excessive alcohol consumption can have adverse effects on the body. Therefore, it is recommended to adjust alcohol intake according to individual health conditions in daily life.

Perceptual disturbances: heightened sensitivity or reduced responsiveness to sounds, light, and smells; for example, hearing faint noises that do not exist or perceiving colors of objects as abnormal.

Does psychiatric illness require hospitalization?
In general, whether psychiatric treatment requires hospitalization depends on the severity of symptoms and their impact on the safety of the individual and others. If a patient experiences severe hallucinations or delusions, accompanied by impulsive aggressive behaviors, self-harm or suicidal actions, or is unable to eat, sleep normally, and maintain basic daily functioning, hospitalization may be necessary. During hospitalization, systematic medical interventions can rapidly stabilize symptoms and help prevent dangerous incidents.

Can psychosis cause dizziness?
In general, mental illness itself may not directly cause dizziness, and judgment should be made according to specific circumstances. Some patients may experience dizziness due to physical symptoms associated with their condition or treatment side effects, but dizziness is less common when only core psychiatric symptoms are present. In daily care, it is important to closely monitor the patient's condition and differentiate whether dizziness is caused by emotional factors, medication, or other reasons.

What are the early warning signs of psychosis?
A series of abnormal manifestations typically occur before the onset of a psychotic episode. These prodromal symptoms primarily involve perception, emotional state, thought patterns, behavior, and social functioning, and specifically include perceptual disturbances, mood fluctuations, disorganized thinking, unusual behaviors, and social withdrawal. These warning signs do not appear all at once and vary in severity from person to person.

What are the warning signs of psychosis?
Before the onset of psychosis, there are often clear abnormal signs. These prodromal symptoms typically involve dimensions such as perception, emotion, thinking, behavior, and social functioning, including perceptual disturbances, emotional dysregulation, disorganized thinking, unusual behavior, and social withdrawal. The timing and severity of these early symptoms vary from person to person. Timely recognition and appropriate scientific intervention can provide strong support for subsequent improvement.
