The Definition of Mad

When someone says 'mental disorder' many people associate it with madness. This is truly not the case. There are many states of mental disorder where the sufferer is not clinically insane.

Madness essentially means psychosis, being out of touch of reality and not being capable of rational and controlled thought. A person in psychosis may have irrational delusions and hallucinations that illustrate this imbalance in conscious and unconscious mind.

Schizophrenia

Schizophrenia can effect mind and personality. In severe cases, the sufferer believes that 'something' is in control of them, and that they have lost control of themselves.

Affective Mood Disorder

  • Mania - The sufferer is overly cheerful and can possibly appear as if they are under the influence of alcohol
  • Depression - Where beliefs and perceptions are unclear & unproductive

Obsessive & Compulsive Disorder

A mental disorder where the sufferer must undergo meticulous rituals to live their normal lives, such as excessive washing of their skin and hair. If the sufferer cannot do this, anxiety kicks in as a "withdrawal symptom" until they allow themselves to repeat the ritual once again.

Phobias

A preconception about a given situation or object, such as a fear of snakes or being in high places. A huge diversity of phobias have been discovered by psychologists.

Depressive Neurosis

The classic case of depression where depression is the primary emotion in the sufferer, resulting in a lack of motivation and self-esteem to be functional in society and to themselves.

Physical Disease

Not only can the way the brain works be affected by disorders, the physical components of the brain can also be infected by pathogens. Dementia is such a physical disease, where the long term memory of the sufferer is broken down due to the physical components of the brain and nervous synapses degrading over time.

Drugs for Mental Disorders

A wide range of drugs are now available for those suffering mental disorders, though many people face a psychological barrier when it comes to taking medication to cure their 'soul'. Many of the drugs used prove addictive which in turn can also lead to further psychiatric problems.

However, psychotherapy is an alternative communicative treatment designed to get the patient to understand themselves better. This can be combined with drugtherapy, and eventually develop the patients' self realisation into a moreproductive and positive state. Medicinal neurology is a fairly new area of medicine.
