Understanding Psychiatric Disorders

Psychiatric disorders are mental, emotional and behavioral disorders, comprising a broad range of problems with different symptoms. They are generally characterized by some combination of abnormal thoughts, emotions, behavior and relationships with others.

Mood and anxiety disorders are serious mental health conditions that have a considerable impact on a person’s personal and family life, as well as on their ability to function at work or school.


Mood disorders are characterized by periods of extreme mood, whether very low mood (depression), or opposing periods of elevated mood and low mood (bipolar disorder). People with depression feel sad, empty, or hopeless, and lose interest and pleasure in activities, for long periods of time. They are also likely to have cognitive symptoms, such as difficulty concentrating and making decisions. People with bipolar disorder have times when they seem abnormally cheerful and full of energy, which can lead to impulsive and risky behaviors.


Anxiety disorders are characterized by excessive, unrealistic worry. People with generalized anxiety disorder, for example, have uncontrollable worries about various everyday things, such as their responsibilities, finances, and health. Post-traumatic stress disorder can develop following a traumatic event, such as exposure to violence or a vehicle accident, and may result in recurring nightmares and flashbacks.


Mood and anxiety disorders are relatively common, and it is not unusual for one person to suffer from multiple disorders. Symptoms differ from person to person but, with treatment, most people are able to return to their normal lives.

Psychotic disorders, such as schizophrenia, are serious mental health conditions associated with altered ways of thinking and perceiving things. They are characterized by ‘psychosis’ in which a person loses touch with reality. People may experience delusions – strong but false beliefs, such as the belief that someone is trying to harm them or that someone is putting thoughts into their head. People may also experience hallucinations – false information from their senses, such as hearing voices or seeing things that are not really there. In addition, people with psychotic disorders may have reduced emotions, difficulty in speaking, and reduced feelings of pleasure or interest.


Psychotic symptoms and disorders may be induced by certain medications and illicit drugs, may be a consequence of another medical condition, or may be due to structural changes or chemical imbalances in the brain. These disorders are commonly misunderstood by the general public, making them a source of stigma and discrimination.


Psychotic disorders require treatment and are often highly disabling, with a considerable impact on a person’s personal and family life, as well as on their ability to function at work or at school.
