Different types of mental illness

Bipolar affective disorder

It is one of the common mental illnesses that affects the mood of a person. Also called manic depression, mental illness like this presents itself with mood swings. You may experience sudden changes in your mood from being overjoyed to feeling sad for no reason. These fluctuations are typical symptoms noticed in individuals suffering from bipolar affective disorder.

Anxiety disorders

People with this disorder face anxiety attacks when faced with unpleasant situations or objects. It is often diagnosed with panic attacks accompanied by the following symptoms:

  • Profuse sweating
  • Rapid beating of the heart
  • Dizziness

In some cases, social phobia is also common among anxiety disorders. Here, you face anxiety attacks and get nervous when you are around other people. There is a constant fear of being judged by people around you.

Obsessive compulsive disorder

This disorder is characterized by getting obsessed with intrusive thoughts or behaviors. If affected, you may have the same thoughts repetitively, which then turns into an obsession. Sometimes, even if the thoughts are unreasonable, you may not be able to control your actions [2]. By taking proper medications or therapy, you may be able to overcome or control it.

Post-traumatic stress disorder

This mental illness is a result of any unexpected event that may have occurred in your life. If you have experienced any traumatic event, you may experience this disorder. Common triggers include:

  • An accident of a loved one
  • Sexual assault
  • Torture
  • Natural disasters you have witnessed.

Getting lost in thoughts or being startled often are the typical symptoms of this disorder.

Psychotic disorders

One of the classic symptoms of this disorder is hallucinations. Seeing things or hearing sounds that may not be real is the first sign. Delusions are next and may cause you to stick to certain false beliefs. You may not be ready to accept the actual facts.

One example of a psychotic disorder is schizophrenia. A schizophrenic individual is unable to connect with the real world. Psychosis may also occur in people that have mood disorders or are in a drugged state. It is a very serious issue and can be quite difficult to control without proper care. People with psychosis will not be as social and may even have self-destructive tendencies.

Major depressive disorder

This is a disorder where you may lose all hope in life. Individuals experiencing this condition are also prone to get suicidal tendencies. Some of the typical symptoms of depression include [3]:

  • Feeling worthless
  • Loss of appetite
  • Poor concentration
  • Loss of interest
  • Poor appetite
  • Fatigue

Following psychotherapy and behavior therapy may improve this condition. Do note that it can be hard to pinpoint the exact cause. It could be stress or genetics that could alter the brain enough to disrupt mood stability. In any case, getting care is important to overcome this condition.
