About 5.5 million Americans suffer from this disease. There is no cure and it is not easily managed. Alzheimer’s disease is the most common form of dementia. The term is used for a variety of diseases and conditions when nerve cells (called neurons) in the brain die or function abnormally. It’s the condition of forgetfulness, loss of ability to reason and think clearly. As the population ages more and more people suffer from this disease. The increase in newly diagnosed cases each year proves that it is not possible to ignore this problem any longer. Alzheimer’s…show more content…
These hemispheres are each divided into four major lobes. The frontal lobes are responsible for speech, judgment, planning, muscle movements, problem solving, and creativity. The parietal lobes (behind the frontal lobe) deal with reading, mathematics, temperature, taste and touch. The temporal lobes (located on each side) are associated with memory, language, hearing, meaning, learning and sound. The occipital lobes (the lower back head region) are employed with special recognition and vision. The cerebellum (behind the brain stem) deals with balance, movement coordination, and posture. AD targets specific nerve cells (neurons) in the cerebellum. These lost neurons are regenerated by the hippocampus of the brain. It also regulates emotions and is a part of the cerebral cortex that deals with smell. During Alzheimer’s disease the hippocampus and thalamus shrink in size. The thalamus is located in the center of the brain, bellow the corpus callosum. The hypothalamus controls major hormone releases, food and water ingestion, temperature regulation, sexual behavior/reproduction, the body’s biological clock, stress and emotional response. The hypothalamus is usually affected early by AD. The pituitary gland is more active in Alzheimer’s, causing the growth hormone (GH) response to be higher. Hormones that are secreted by the pituitary gland control neurons in the brain. The brain stem basically connects the brain and spinal cord. It has three parts: the midbrain, the pons and the medulla. The mid brain helps in vision and eye movement, hearing, body motion, and voluntary motor function. The pons is linked to sleep, consciousness, movement and posture. The medulla deals with blood pressure, breathing and heartbeat (Naheed 12-14). Alzheimer’s-related brain changes may begin 20 years or more before symptoms occur, when communication between neurons in the brain is disrupted. Neurons begin to work less efficiently, because of abnormal deposits of protein
