List of Psychological Disorders and Their Symptoms:

1. Neurodevelopmental Disorders

This list of psychological disorders mainly focuses on the issues that typically arise during infancy, childhood, or adolescence. Some of the mental conditions in this mental disorders list can be completely resolved through proper interventions. While others are chronic, their extent can also be reduced through adequate interventions as well.

  • Intellectual Disabilities:

Formerly it was referred to as mental retardation, but now the terminology has changed. This usually develops before the age of 18, it can be seen in the form of limitations in a child’s intellectual and adaptive behaviors and is assessed through IQ tests. It is believed that children with IQ scores below 70 indicate the presence of certain limitations.

  • Communication Disorders:

It is characterized by a significant deficit to communicate. This can be seen in areas of speech, comprehension, and usage of language. DSM-5 identifies four types of communication disorders viz., childhood-onset fluency disorder (stuttering), language disorder, social (pragmatic) communication disorder, and speech sound disorder.

  • Autism Spectrum Disorder:

The important diagnostic criteria for autism spectrum disorder are- restrictive and repetitive patterns of behaviors and lack of social interaction. This interferes with daily life functioning of the children.

  • Attention-Deficit/Hyperactivity Disorder:

2. Schizophrenia Spectrum and Other Psychotic Disorders

The most dramatic disorder in this list of mental disorders is schizophrenia. It affects the feelings, thoughts, and behavior of an individual just like other disorders in this psychological disorders list but, this is one with long-term conditions and complexities. Schizophrenia is an umbrella term with many disorders of psychotic nature falling under it. The person experiences either of the following symptoms:

Positive Symptoms:

The word positive here denotes an excess of emotions, thoughts, and behavior. This is further classified into four types

  • Delusions:

There are false beliefs about a stimulus that is repetitive and persistent. The delusions are psychotic in nature and interfere in the day-to-day life of the person.

  • Hallucinations:

They are false sensory experiences with no basis in the external world. They take place when the person is wide awake and not under the influence of any drug. These false and psychotic sensations are felt through all our five senses- hearing voice (auditory hallucination), seeing things (visual hallucination), tingling sensations on the skin (tactile hallucination), smelling things (olfactory hallucination) and smelling things (gustatory hallucinations).

Unlike basic speech errors made many of us, psychotically disorganized speech is beyond understanding in its nature. There are no linkage or language rules applied to speech that is being conveyed.

  • Disorganized behavior:

The behavior demonstrated are not goal-directed or in content with the given situation. Thus, leading to problems in the daily functioning of an individual’s life.

Negative Symptoms:

The word negative here denotes a lack of emotions, thoughts, and behavior. The four types of negative symptoms of schizophrenia are:

  • Flattened affect:

People with flattened effect generally show limited or no emotions at all. They respond with limited emotions even in emotional situations or disturbing images, making them look emotionless.

  • Reduced speech:

It can be assessed on two parameters, either the individual is not fluent in speaking as s/he was or the speech (amount) reduces noticeably below than the usual.

  • Lack of initiative:

The individual here loses all the will to engage
