Brain development

Studies of people with schizophrenia have shown there are subtle differences in the structure of their brains.

These changes aren’t seen in everyone with schizophrenia and can occur in people who don’t have a mental illness. But they suggest schizophrenia may partly be a disorder of the brain.


Neurotransmitters are chemicals that carry messages between brain cells. There’s a connection between neurotransmitters and schizophrenia because drugs that alter the levels of neurotransmitters in the brain are known to relieve some of the symptoms of schizophrenia.
Research suggests schizophrenia may be caused by a change in the level of two neurotransmitters: dopamine and serotonin.

Some studies indicate an imbalance between the two may be the basis of the problem. Others have found a change in the body’s sensitivity to the neurotransmitters is part of the cause of schizophrenia.

Pregnancy and birth complications:

Research has shown people who develop schizophrenia are more likely to have experienced complications before and during their birth, such as:

  • a low birth weight
  • premature labour
  • a lack of oxygen (asphyxia) during birth.

It may be that these things have a subtle effect on brain development.

Drug abuse

Drugs don’t directly cause schizophrenia, but studies have shown drug misuse increases the risk of developing schizophrenia or a similar illness.

Certain drugs, particularly cannabis, cocaine, LSD or amphetamines, may trigger symptoms of schizophrenia in people who are susceptible.

Using amphetamines or cocaine can lead to psychosis, and can cause a relapse in people recovering from an earlier episode.

Three major studies have shown teenagers under 15 who use cannabis regularly, especially “skunk” and other more potent forms of the drug, are up to four times more likely to develop schizophrenia by the age of 26.
