Neurotic disorders are less severe psychiatric disorders where patients experience excessive or prolonged emotional reactions to stress. These disorders are not caused by organic brain diseases and do not involve hallucinations or delusions. Some examples include somatoform disorder, phobic anxiety disorder, obsessive compulsive disorder, and post-traumatic stress disorder. Phobic anxiety disorder is characterized by irrational fears of specific objects, situations, or activities. Treatment involves psychotherapy, relaxation techniques, medication, and addressing underlying negative thoughts contributing to anxiety.
