Neurosurgeon and Patient :: Neurology Medical Health Essays

Neurosurgeon and unhurriedBrain injury is an unexpected and complex disability. The brain stinkpot be damaged in many ways as a way out of an accident, a stroke, alcohol or drug abuse, tumors, poisoning, infection 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 vital and complex variety meat in the human body. It is where we store our thoughts, feelings and all of our learned behavior. The parietal lobe is the lobe of the rational cortex that is at the top of the brain, which processes information in reference to touch, taste, pressure, pain, and change and cold. The parietal lobes displace be divided into two functional regions. angiotensin converting enzyme involves sensation and perception and the other is concerned with integrating sensory input, in the first place with the visual system. The first function integrates sensory inform ation to form a single precept (cognition). The second function constructs a spatial coordinate system to represent the world around us. Individuals with damage to the parietal lobes frequently show striking deficits, such as abnormalities in body depiction and spatial relations (Kandel, Schwartz & Jessel, 1991).Damage to the left parietal lobe can result in what is known as Gerstmanns Syndrome. This syndromes effects include right-left confusion, difficultness with writing (agraphia) and difficulty with mathematics (acalculia). It can also yield disorders of address (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 dressing and washing. Right case damage can also motion difficulty in devising things (constructional apraxia), denial of deficits (anosagnosia) and drawing ability. (Kimura,D.1977) Bi -lateral damage (large lesions to both 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 pictorial matter (simultanagnosia), and the inability to accurately reach for an object with visual guidance (optic ataxia). additional deficits (primarily to depot and personality) can occur if there is damage to the area surrounded by 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.
