SIGNS & SYMPTOMS OF MENTAL ILLNESS

DISORDERS OF

PERCEPTION

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

• Hyper aesthesia: Increased intensity of sensations, seen in intense emotions and hypochondriacal personalities.

In hyper aesthesia sounds appear louder, colors brighter ,and pain unbearable .

• Illusions: Misperceptions or 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 .

• 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.

Types

Auditory hallucinations (voice, sound, noise).

is a form of hallucination that involves perceiving sounds without auditory stimulus.

Types of auditory hallucination:•Second-person hallucinations: voice speaking to the person addressing him as “you”.

•Third-person hallucinations: voice talking about the person as “he” or “she”:

•Thought echo: hearing one’s own thoughts spoken aloud.

• Visual hallucination is the seeing of things that are

not there .

Olfactory hallucinations is the phenomenon of smelling odors that are not really present. The most common odors are unpleasant smells such as rotting flesh ,vomit, urine, feces, smoke, or others

Gustatory hallucination is the perception of taste without a stimulus.

• 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.

• somatic hallucination

Somatic hallucinations refer to sensations or perceptions concerning body organs that have no known medical cause or reason, such as the notion that one's brain is radioactive.

• Imperative hallucination: voices giving instructions to patients, who may or may not feel obliged to carry them out.

• ‘Thought echo’ : hearing one’s own thoughts being spoken aloud; the voice may come from inside or outside the head.

• Scenic hallucinations: hallucinations in which whole scenes are hallucinated like a cinema film; more common in psychiatric disorders associated with epilepsy.

• Lilliputian hallucinations: A term used to denote a

hallucination featuring miniature individuals, animals, objects, or fantasy figures.

• Autoscopy (phantom mirror image): the patient sees himself and knows that it is he. Seen in normal subjects when they are depressed or emotionally disturbed.

• ‘Negative autoscopy’: the patient looks in the mirror and sees no image; in organic states.

• Internal autoscopy: the subject sees his own internal organs.

• Extracampine hallucinations: a hallucination which is outside the limits of the sensory field.

• Extracampine hallucinations are hallucinations beyond the possible sensory field.

• e.g., 'seeing' somebody standing behind you is a visual extracampine hallucination experience.

• Hypnagogic hallucinations: hallucinations when falling asleep.

• Hypnopompic hallucinations: hallucinations when waking from sleep.

• Flight of ideas Flight of ideas describes excessive

speech at a rapid rate that involves fragmented or unrelated ideas. It is common in mania. It has also been described in schizophrenia and ADHD

• Pressure of thoughts: Rapid abundant varying thoughts associated with pressure of speech and flight of ideas.

A manifestation of a thought disorder whereby the patient's responses do not relate to the interviewer's questions, or one paragraph, sentence, or phrase is not logically connected to those that occur before or after.

Example: I sang out for my mother …… for this to hell I went…how long is road …

Tangentiality: It is a form of derailment. Wandering from the topic

and never returning to it or providing the information requested.
