The Effects Of Stroke

22.11.05

Agnosia = no recognition.
Sensory dysphasia = no understanding, speaks nonsense, has no realisation of this.
Motor dysphasia = understanding, telegrammatic/no speech (Brocca's dysphasia).

Functions of other lobes
TEMPORAL LOBE
• Dysphasia; memory. Therefore, lesion in temporal lobe affects memory (ability to register, retain and recall)
• Also, deeper memory eg. Alzheimer's.

PARIETAL LOBE
• Mixed dysphasia - inability to speak in absence of sensory and motor deficit.
• Agnosia.
• Dyspraxia - inability to carry out sequence of voluntary actions in absence of sensory and motor deficit.
• Topographical disorientation - cannot visualise.
• Body image - loss of awareness of body.

LIMBIC AND FRONTAL LOBES
Limbic lobe associated with anger, love, sex, sadness etc. Emotions channelled into frontal lobe.

Frontal lobe captions information from limbic lobe, sifts it out, leading to reasoning:
• Intellectual reasoning.
• Conceptual reasoning.
• Emotional reasoning.
• Speech fluency.
STROKE CAN CHANGE ANY OF THESE FUNCTIONS.

Do not forget: DEPRESSION.
• Despair, blackness etc.
• Physiological changes as well as suicide
• Males three times more likely to die.
• Females two times more likely to die.
• BUT 80% cure rate - TREATABLE.
• Frequently missed and rarely treated.
