Delusion

A false belief which cannot be explained by cultural norms and that the patient often holds strongly. There are many forms, two of which are grandiose (e.g., the belief that one is God) and persecutory (e.g., thinking that aliens are trying to kill him or her). Delusions are a form of psychosis which often occur in the course of a severe mental disorder, such as schizophrenia or bipolar disorder.

The belief that aliens reside in one's nose is a delusion.

Clinical depression

Also referred to as major depressive disorder, major depression, unipolar disorder or simply depression, this illness is a psychiatric condition marked by severe feelings of despondency and dejection, typically accompanied by changes in eating and sleeping habits, anhedonia (loss of interest), fatigue, somatic pain and, at the extreme, suicide ideation. Also occurs in bipolar disorder (depressed phase).

Clinical depression is a serious mental illness and quite different to the ordinary sadness we all experience from time to time.

Mood disorder

A mood or affective disorder is a major type of mental illness in which emotions are significantly disturbed. Examples include clinical depression and the more severe bipolar disorder.

Obsessive-compulsive disorder

Also known as OCD, obsessive-compulsive disorder is a neurotic mental illness in which intrusive, negative thoughts and/or impulses which regularly enter the person's mind (obsessions) are counteracted by repetitive acts or rituals performed to alleviate the anxiety and general distress created by these obsessions. It is possible to qualify for a diagnosis of OCD if only obsessions or compulsions are present, although the vast majority have both.

Obsessive-compulsive disorder is much more than being quirky or a bit of a neat freak.

Mania

A state of mental and physical overactivity characterised by pressured speech, racing thoughts, decreased need for sleep, extreme irritability or elation and, not infrequently, delusions and hallucinations (i.e., psychosis). It is most commonly associated with bipolar disorder, a serious mental condition in which sufferers alternate between mania and depression.

True mania is a terrifying thing to witness and rarely forgotten.
