  • 3. NEUROANATOMICAL PERSPECTIVES Cerebral white matters are reciprocally connected to parietal, Temporal and occipital lobes in addition to extensive subcortical connection. Ratio of white to grey matter is significantly higher in the right than the left hemisphere particular is in frontal lobes. Groups of white matter pathways are recognised which completely myelinate in II or III decade. They are projection, Commissural and Association fibres. “ He who cannot forgive others destroys the bridge over which he himself must pass” - Annoy
  • 4.  Salient physiological aspect is the presence of myelin which results in marked increase in axonal conduction velocity. The potential recovery is grater in white matter disorders than is grey matter disorders. Finally white matter figures prominently in a general theory of brain-behaviour relationships due to its multiple networks of interconnected neurons that subservice various behavioural functions. “By Nature All Men/ Women are alike but by Education widely different” - Chinese

Behaviour Reduced cholinergic function Enhanced cholinergic functionAgitation Increased in AD increased in AD Reduced by physostigme in treated with anticholinergic AD agentsPersonality Apathy is common in ad reduced Apathy in AD is reduced by affinitive behaviour induced by Tacrine Anticholinergic agents Knowledge without action is useless; Action without knowledge is foolish

THE EVALUATION OF PSYCHIATRIC SYTEMS:  Medical history  For hyper metabolic syndromes  For aggression  Psychiatric history  For depression  For hyper metabolic syndromes  Medication  Physical examination  Mental status  For suicide attempt  Laboratory investigation  For anxiety  For hyper metabolic syndromesIt is the providence of the knowledge to speak and it is the privilege of the wisdom to listen - Hodly’s

CLINICAL CLUES:  If sudden, it is likely to be acute encephalopathy  If the symptoms are chronic, hallucinations and delusions are added and tend to be associated with dementia or static Encephalopathy  Psychosis with delusional belief are common in subcortical disorders associated with extrapyramidal symptoms,A true com itm is a heart felt prom to y m ent ise ouarself fromwhich y will not ou back down - D.

  • 30. Syndrome/ Etiology CharacteristicsTrasient global amnesia Anteto grade amnesia during episode Duration of a few hours History of trauma Brief period of retrograde amnesia Variable period antero gade amnesiaHead trauma History of trauma Brief period of retrograde amnesia Variable period antero grade amnesiaAlcohol related blackout Aassociated with prolonged alcohol abuse and severe intoxication “Motivation is the Spark that lights the Fire of Knowledge and fuels the engine of Accomplishment”

Syndrome/ Etiology CharacteristicsDissociative fugue Sudden unexpected travel away from home inability to recent pasts Loss of personal identityAmenesi a associated Often PCA distribution infarcts (bilateral)with stroke Hypoxic episode Often accompanied by focal deficits such as hemianpsia, cortical blindness visual agonsia.Dementia Memory impairment in the setting of other cognitive deficits that impair daily living.Electroconvulsive therapy Only after repeated sessions Deficits resolve within 6 months The art of medicine is caring for the heart of the patient

TREATMENT Memory impaired - complete and behavior rehabitation Wernicke’s Encephalopathy - Thiamine TGA- No independent risk factor for stroke - 94% TGA - 5-7% Can develop epilepsy Dissociate amnesia – psychiatrist management Success in life is a matter not so much of talent and opportunity as of concentration and perseverance - C.W. Wendte
  • 34. CONCLUSIONS   Psychiatric consultation may clarify the presence  of a primary psychiatric condition  “The great majority of us are required to live a life of constant systematic duplicity. Your health is bound to be affected if day after day you say the opposite of what you feel; if you grovel before what you dislike and rejoice at what bring you nothing but misfortune. The nervous system is not just a fiction it is part of our physical body and our soul exists in space and inside us; like the teeth in our mouth. It can’t forever be treated with impunity,”We possess by nature the factors out of which personality can be made, and to organize them into effective personal life is every man’s primary responsibility - Harry Emerson Fosdick
