Neurosurgeon and PatientBrain injury is an unexpected and complex disability. The intelligence understructure be maltreatd in many ways as a result of an accident, a stroke, alcohol or drug abuse, tumors, poisoning, contagious disease and disease, hemorrhage, near drowning, AIDS, and a number of other things such as Parkinsons disease, Multiple Sclerosis, and Alzheimers disease. The human brain is one of the most snappy and complex organs in the human body. It is where we store our thoughts, feelings and all of our intentional behavior. The parietal lobe is the lobe of the cerebral cortex that is at the top of the brain, which processes discipline in reference to touch, taste, pressure, pain, and heat and cold. The parietal lobes can be divided into deuce functional regions. One involves sensation and perception and the other is concerned with integrate sensory input, primarily with the optic system. The first function integrates sensory information to form a single p recept (cognition). The second function constructs a spatial coordinate system to represent the world around us. Individuals with price to the parietal lobes often show striking deficits, such as abnormalities in body image and spatial relations (Kandel, Schwartz & Jessel, 1991).Damage to the left parietal lobe can result in what is known as Gerstmanns Syndrome. This syndromes solvents involve right field-left confusion, trouble with writing (agraphia) and difficulty with mathematics (acalculia). It can alike yield disorders of language (aphasia) and the inability to perceive objects normally (agnosia). Damage to the right parietal lobe can result in neglecting part of the body or space (contralateral neglect), which can impair many self-care skills such as medical dressing and washing. Right side damage can also cause difficulty in making things (constructional apraxia), denial of deficits (anosagnosia) and drawing ability. (Kimura,D.1977) Bi-lateral damage (large les ions to two sides) can cause Balints Syndrome, a visual attention and motor syndrome. This is characterized by the inability to voluntarily control the gaze (ocular apraxia), inability to integrate components of a visual scene (simultanagnosia), and the inability to accurately reach for an object with visual guidance (optic ataxia). Special deficits (primarily to memory and personality) can occur if there is damage to the area between the parietal and temporal lobes. Left parietal-temporal lesions can effect verbal memory and the ability to recall strings of digits (Warrington & Weiskrantz, 1977reland et al.
