Individuals with psychosis either experience hallucinations or delusions. Hearing or seeing things that are not actually present is called hallucinations. Seeing things or a person who is not present is called visual hallucinations, and hearing someone shouting or some other random noise is called auditory hallucinations.

The best thing to do is to consult a psychiatrist immediately if you notice a loved one or relative showing such symptoms.

How Is Psychosis Diagnosed?

The doctor may perform an EEG or brain scan to rule out brain-related physical causes. Once they are ruled out, the doctor will pinpoint a mental illness as the cause based on family history, medical history, personal history, and physical examination.

What Are the Treatment Options for Psychosis?

For psychosis, earlier the treatment is initiated, better is the outcome and quality of life in the long run. Treatment includes:

Medications - Psychiatric medications help improve symptoms, and can make other treatments more effective. The doctor might prescribe some of the following medicines:

  • Antidepressants - they treat symptoms such as hopelessness, sadness, and lack of energy.

  • Anti-anxiety medications - these drugs reduce agitation and sleep problems.

  • Mood-stabilizers - these medicines help in stabilizing the mood of patients with bipolar disorder.

  • Antipsychotic medications - are most commonly prescribed for schizophrenia and bipolar patients.

Psychotherapy - Otherwise called talk therapy, is when you talk to a mental health provider about your problems and symptoms. With the help of this therapy, patients learn ways to cope with stressful situations in a healthier way.

Brain-stimulation treatments - It is only employed when there is no improvement even after medications and psychotherapy. This includes:

  • Electroconvulsive therapy.

  • Vagus nerve stimulation.

  • Repetitive transcranial magnetic stimulation.

  • Deep brain stimulation.

Treatment for substance or alcohol addiction - As substance addiction commonly occurs with mental disorders, treatment is needed to break this addiction.

Family education and awareness programs - You need to work together with the mental health professional in deciding which treatment is best for you. In severe cases, a loved one will have to make all the decisions until you recover enough to make your own decisions.

A person with a mental illness is difficult to comprehend and handle for someone who has never been exposed to one. He/she is sometimes misunderstood by even their own family and friends. But, it is crucial to realize that they do not want the illness or imagine it in their head. Just like any other physical illness such as fever, having a mental illness is beyond their control and does not mean they are weak. They do better with reassurance and non-judgemental involvement from close members. If your loved one suffers from psychosis, make sure you understand the condition thoroughly. That is the first step in treating them with success.
