Deciding what is normal and what is abnormal is a value judgment. Psychological disorder judgments are based on cultural values, social trends, political forces, as well as scientific knowledge. A psychological disorder, also called mental disorder, is a pattern of feelings, thoughts and behavioral symptoms that impact multiple life areas and create distress for the person experiencing these symptoms. Here are various types of such disorders and how they affect an individual’s life and the people around them:

Somatoform disorders include physical symptoms without physiological basis. Physical complaints involve four or more sites on body (at least two gastrointestinal, one sexual, one pseudo neurological), doctor-shopping, unnecessary operations, anxiety, and depression.

7. Anxiety disorders – when fear takes over

anxiety disorder

This disorder includes a range of conditions characterized by the experience of anxiety or fear. This is a broader category and includes phobias, post-traumatic stress, panic and obsessive–compulsive disorder, and also conditions where there appear to be physical symptoms (such as intense pain) because of the anxiety. Although the experience of anxiety is different for everybody.

It is typical for people to experience feelings of terror or dread and a loss of control, the constant and strong thought that they are going to faint, vomit or even die, to feel dizzy, to have trouble breathing and to start sweating. The behavioral symptoms of phobias are concentrated around avoiding the thing that the person is afraid of. It is this urge to avoid the fear stimulus that causes the problems of daily function that might bring a person to the attention of a psychologist or psychiatrist.

6. Dissociative disorders

dissocitaive disorder

Dissociative disorders are partial or total loss of personal information (due to traumatic event). There are various types of it:-

Localized amnesia—loss of all memory for a short time (most common type).

Selective amnesia—loss of details about an incident.

Generalized amnesia—total loss of memory for past.

Systemized—loss of memory for selected types of information.

Continuous amnesia—inability to recall any events from a specific time until present (least common type) which results into usually incomplete change of identity,recovery is usually abrupt and complete. Symptoms include feelings of unreality and perceptual distortion, great anxiety, physical or psychological stress, and depression.

5. Personality disorder – a way of being

personality disorder

These are disorders of people’s basic character structure – so there is no ‘normal functioning’ to return to. The personality disorders themselves are people’s ‘normal’ way of functioning, and appropriate treatment means learning entirely new ways of being. All personality disorders have a number of things in common. They are:-

Longstanding – i.e. begin at a relatively early age.

Chronic – i.e. continue over time.

Pervasive – i.e. occur across most contexts.

The thoughts, feelings and behaviors which characterize personality disorders are inflexible – i.e. they are applied rigidly and resistant to change and maladaptive– i.e. they don’t result in what the person hopes for. People with personality disorders usually don’t realize they have them. They experience themselves as normal and often feel that the people they interact with are the ones with the problems.

4. Substance use disorders – abuse and dependence

substance use disorder

The recurrent use of drugs and alcohol may result in a substance use disorder. It involves symptoms like dependence and abuse, intoxication, delirium, and withdrawal. It occurs by recurrent use of drugs or alcohol over 12 months leading to impairment or distress. Maladaptive behaviors or psychological changes are evident, gradually unpleasant states worsen and leads to more drug use and self-destructiveness. Common impairments include:-

Failure to fulfill major role obligations – e.g. constantly late to or absent from work.

Recurrent indulgence in dangerous situations – e.g. rash driving.

Frequent substance-related legal problems – e.g. arrests for disorderly conduct.

Social and interpersonal problems – e.g. conflict with partner or other family members.

This disorder is most prevalent among youths and young adults. Adult lifetime prevalence for controlled substances is 6.2 percent which is particularly greatest for marijuana.

3. Eating disorders – bulimia and anorexia

eating disorder

Anorexia nervosa: refusal to maintain a body weight above the minimum normal weight for one’s age and height due to an intense fear of becoming obese that does not diminish with weight loss, body image distortion and (in females) the absence of at least three consecutive menstrual cycles otherwise expected to occur.

Bulimia nervosa: recurrent episodes of binge eating high caloric foods at least twice a week for three-four months, during which the person loses control over eating. It differs from binge-eating/purging anorexia as for anorexia the weight is under minimally expected levels.
