Psychotic disordersWhat is psychosis? And what is the difference between schizophrenia and drug-induced psychosis?

1What is psychosis?

Psychosis is a condition in which the brain cannot accurately distinguish what is real from what is created by the mind. The person is not “pretending” or “deliberately imagining”; they live what they see, hear and believe as complete reality.

Psychosis is a group of symptoms, not a diagnosis in itself, and it can appear in different illnesses: in schizophrenia, in manic episodes or severe depression, after the use of certain drugs, and it may even appear with severe sleep deprivation or with some physical illnesses and medications. This is why a doctor always looks for the cause before making a diagnosis.

The US National Institute of Mental Health notes that psychosis most often first appears in the late teens through the mid-twenties, the very years when a young person is building their studies, work and relationships, which is why recognizing it early is critically important.

2What is the difference between hallucinations and delusions?

These are the two best-known symptoms of psychosis, and families often confuse them. The simple idea: hallucinations are a disturbance of perception, meaning the senses, while delusions are a disturbance of belief, meaning how a person interprets the world.

It is important for the family to know that arguing with a delusion does not remove it. Trying to “convince” the person that what they believe is untrue often increases their fear and their sense that the people around them have become part of the plot. More helpful is acknowledging their feelings (“I understand you're scared”) without confirming the idea itself or mocking it.

3What does psychosis look like from the inside?

Many people who have been through a psychotic episode describe it starting with a vague feeling that “something has changed” in the world: sounds are louder, glances carry hidden meanings, and coincidences seem like messages aimed at them. Then these feelings gradually turn into convictions, and fear becomes the dominant feeling.

I didn't know I was ill; I was sure everyone knew a secret they weren't telling me, and that was more terrifying than anything else.

This is why many people do not seek help on their own at first: reduced insight into the illness is part of the condition itself, not stubbornness. That is why it matters for the family to notice the change and take the initiative in asking for an assessment.

4Types of psychotic disorders

Eradah's guide covers two disorders from this family, each with separate pages on symptoms, treatment and more. Here is a short card for each:

5What is the “schizophrenia spectrum and other psychotic disorders”?

Modern medical classifications, such as the DSM-5 diagnostic manual and the international ICD-11, group these disorders into one spectrum, because they share symptoms of psychosis and differ in duration, cause and pattern. The main conditions in this spectrum include:

• Schizophrenia: psychotic symptoms lasting a long time with a decline in daily functioning, and the best known disorder in the family.
• Brief psychotic disorder: a sudden, short episode after which the person usually returns to their previous state, and which may follow severe stress.
• Delusional disorder: a fixed delusion on a particular theme, such as jealousy or persecution, with daily functioning that looks relatively normal.
• Schizoaffective disorder: psychotic symptoms that overlap with clear episodes of depression or mania.
• Substance- or medication-induced psychosis: psychotic symptoms directly caused by a substance or medication, going beyond the usual effect of intoxication or withdrawal.

Psychosis can also appear within episodes of bipolar disorder or severe depression, and the doctor then treats it as part of the mood disorder.

6What is the difference between drug-induced psychosis and schizophrenia?

This is one of the most important questions we meet at Eradah, because many families face a son's first psychotic episode after using crystal meth (shabu), Strox or hashish. The key difference is in the cause and the course:

The US National Institute on Drug Abuse notes that chronic methamphetamine (shabu) use can cause psychotic symptoms such as paranoia and hallucinations, which may last for months or years after stopping, and that synthetic cannabinoids (Strox and Voodoo) can cause acute psychotic episodes. You can find the details in the guide to drug-induced psychosis, and on the page about schizophrenia and addiction for when the two illnesses occur together.

7Psychotic disorders in numbers

These figures come from the World Health Organization's schizophrenia fact sheet, and they reveal two problems: the illness is not as rare as many think, and the treatment gap is huge, not because treatment does not exist but because of stigma and delays in seeking help.

8Why does early intervention change the course of the illness?

Every month that passes with untreated psychosis means more decline in studies, work and social life, and may make the response to treatment slower. This is why modern health systems use “early intervention in psychosis” programs that combine medication, psychological treatment, family support and help returning to study or work, and the US National Institute of Mental Health describes them as the established approach to treating psychosis in its early stages.

Before a full episode, early signs that deserve attention often appear:

• Growing suspicion of others or a feeling of being watched for no clear reason.
• Withdrawal from friends and family and spending long periods alone.
• Strange ideas or a sudden interest in obscure subjects.
• Neglect of personal hygiene and a sharp decline in study or work.
• Marked sleep disturbance, or staying awake for days.
• Difficulty telling reality from imagination, or in organizing thoughts.

This list is for awareness and is not a diagnostic tool. A single sign can have many causes, but more than one sign together deserves a psychiatric assessment.

9Are psychotic disorders treatable?

Yes. The plan usually relies on antipsychotic medication chosen by the psychiatrist, who monitors its side effects, along with psychological therapy, family education and rehabilitation for returning to daily life. With drug-induced psychosis, addiction treatment becomes an essential part of the plan, because returning to substance use is one of the strongest causes of recurring episodes.

You can find the details on the pages for schizophrenia treatment and drug-induced psychosis treatment.

10Myths that increase stigma, and the facts

The World Health Organization stresses that the stigma surrounding schizophrenia leads to isolation and discrimination in work, education and health care. Using humane language such as “a person living with schizophrenia” instead of hurtful labels is a simple step that makes a big difference to the patient and their family.

11How should a family respond to a person in a psychotic episode?

1. Keep your voice and your surroundings calm, and reduce noise and the number of people in the room.
2. Do not argue with hallucinations or delusions or mock them; acknowledge their feelings and reassure them that you are by their side.
3. Ask simple, clear questions, and avoid sudden touch or quick movements.
4. Calmly ask about any substance they have used, because that changes the treatment plan.
5. Ask for a psychiatric assessment as soon as possible, and do not wait for the condition to “pass on its own.”
6. Know the patient's rights; Egypt's Mental Patient Care Law No. 71 of 2009 regulates admission to hospital and protects patients' rights. This is general awareness information, not legal advice.
