🆚 Go to Comparative Table 🆚

The difference between organic and functional mental disorders lies in the causative factors and the nature of the disorders.

Organic Mental Disorders:

  • Caused by structural defects or physiological dysfunction of the brain.
  • The causative factors are known.
  • Examples include psychoses caused by brain injury, infections, or neurological diseases.

Functional Mental Disorders:

  • Causative factors have not yet been identified.
  • Symptoms are not attributable to any known medical, neurological, or substance-related disorder.
  • Examples include psychoses that are not associated with any diagnosable pathophysiology.

In summary, organic mental disorders can be attributed to specific biological changes, while functional mental disorders have no identifiable cause and are not associated with any diagnosable pathophysiology. Both types of disorders can present with similar symptoms but have distinct underlying causes.
