This document provides definitions and descriptions of key concepts in psychopathology and signs and symptoms of mental illness. It begins by defining psychiatry and psychiatric nursing. It then describes various disorders of perception such as hallucinations and illusions. It covers abnormalities in thinking such as thought disorders, abnormalities in thought content like delusions, and abnormalities in mood and emotion. Finally, it discusses some abnormalities in speech. The document provides detailed information on the classification and clinical presentation of many types of mental disorders.

SYMPTOMS OF

meaningful organization of
sensory data and their
interpretation in the light
of one’s past experience.

7. • Hyper aesthesia: Increased intensity of
sensations, seen in intense emotions and
hypochondriacal personalities.
In hyper aesthesia sounds appear louder,
colors brighter ,and pain unbearable .

misinterpretations of real external sensory
stimuli:
e.g. Shadows may be misperceived as
frightening figures., In a fading light rope is
misperceived as a snake .

8. • Hallucinations:
Perception in the absence of real
external stimuli; experienced as true
perception coming from the external
world (not within the mind).
e.g. Hearing a voice of someone when
actually nobody is speaking within the
hearing distance.

9. Types

10. Auditory hallucinations (voice,
sound, noise).
is a form of hallucination
that involves perceiving
sounds without auditory

Gustatory hallucination is the
perception of taste without a
stimulus.

14. • Tactile hallucinations occurs when someone
feels a sensation on the body that is, in fact,
not present.
Tactile hallucination is the false perception of tactile
sensory input that creates a hallucinatory sensation
of physical contact with an imaginary object.
One subtype of tactile hallucination, formication, is
the sensation of insects crawling underneath the
skin and is frequently associated with prolonged
cocaine use.

15. •somatic hallucination

miniature individuals, animals,
objects, or fantasy figures.

19. • Autoscopy (phantom mirror image): the
patient sees himself and knows that it is

hallucinations beyond the possible
sensory field.
• e.g., 'seeing' somebody standing behind
you is a visual extracampine hallucination
