There are several types of mental diseases which are classified based on their causes. The major ones that are frequently diagnosed include:
* Anxiety: People suffering from these types of mental diseases always respond to situations or certain objects with dread and fear, and always show signs of nervousness or anxiety like sweating and rapid heartbeat. Anxiety disorder is recognized if the situation disrupts the normal functioning of the individual, if the response cannot be controlled by the individual, or if the individual’s response is not right for the circumstance. The following are examples of anxiety diseases: specific phobias, social anxiety disorder, panic disorder, obsessive compulsive disorder, and post traumatic stress disorder.
* Mood disorders: They are equally known as affective disorders and is diagnosed by constant feeling of extreme happiness or sadness, or constant mood swings from extreme sadness to extreme happiness. Some common examples of these types of mental diseases include bipolar disorder, mania, and depression.
* Psychotic disorders: This involves distorted thinking and awareness. A symptom of a psychotic disorder is the feeling of delusion (someone having false beliefs about something in spite of overwhelming evidence that proves him wrong). Another symptom of these types of mental diseases is hallucination (where someone experiences sounds or images that are nonexistent). One very good example of a psychotic disorder is schizophrenia.
