Upon further inspection under microscope, tissue samples are observed and synapses and nerve cell count is severely decreased. Tangles, are also found which our twisted strands of another protein due to nerve cells dying and bunching together. Plaques and tangles are prime suspects in the death and tissue loss in the Alzheimer’s brain. Beta-amyloid is a chemical and is sticky which causes it to gradually build up into plaques. This chemical derives from a larger protein found in the nerve cells with fatty membranes.
Memory loss is usually the earliest and most noticeable symptom (WebMD 2011). The mechanism that causes Dementia is also the mechanism that causes the symptoms to start appearing. Causes and symptoms go hand in hand in the case of Dementia. Worldwide, 35.6 million people have dementia and there are 7.7 million new cases every year (WHO 2012).

When these nerve cells are affected, detrimental damage can happen to your mind and body; one example is called Alzheimer’s disease. Alzheimer’s disease is a fatal type of dementia that causes a gradual and progressive decline in memory, thinking, and reasoning skills. These are a result of a loss in neuronal tissue which causes a narrowing of the gyri and widening of the
During the preclinical stage of Alzheimer’s disease, people are asymptomatic, but unfortunately there are toxic changes taking place in the brain. Abnormal deposits of proteins form amyloid plaques and tau tangles throughout the brain, causing the once-healthy neurons to work less efficiently. Over time, neurons lose the ... ... middle of paper ... ...ww.alz.org/alzheimers_disease_4719.asp (n.d.). Retrieved from http://www.nia.nih.gov/alzheimers/topics/causes (n.d.).

However, AD is not a normal part of aging. The processes which occur in an AD patient are still extensively researched. Nerve cells in the regions controlling the above mentioned faculties are lost and certain neurotransmitters' performance is damaged. The two most affected types of brain cells by AD are neuritic plaques and neurofibrillary tangles. While some neuritic plaques are commonly found in brains of elderly people, they appear in excessive numbers in the cerebral cortex of Alzheimer patients.
• Vascular dementia – Issues regarding the blood vessels can lead to an inadequate blood supply to the brain. Without an adequate blood flow, brain cells will begin to die, causing mild to severe trauma. Because of its frequent symptom of memory loss, vascular dementia seems very similar to Alzheimer’s. • Huntington’s disease – Is a fatally rare condition that causes the gradual deterioration of the nerve cells in the victim’s brain, typically affecting persons fro... ... middle of paper ... ...entia patients. In the later stages of dementia, depression is commonly caused by the reduced function of the chemical transmitter that occurs in the brain.
Alzheimer’s disease is a progressive disease that has behaviors that go along with it. In this disease, the orderly system of the brain becomes damaged and no longer works properly. “The brains of Alzheimer 's disease victims appear shrunken, particularly in large parts of the neocortex, the outer layer of gray matter responsible for higher brain functions such as thought and memory” (“Alzheimer’s Disease,” 2015). It usually begins with minor memory loss of recent events. This memory loss is slowly joined with forgetfulness, cluelessness of hygiene, impaired judgement, and loss of concentration.
The symptoms of Alzheimer's disease are much more severe than simple memory lapses. This chart will kinda help you understand the difference.

As the disease progresses, these symptoms become more severe. Physically a sufferer may experience difficulties in swallowing and chewing, along with experiencing jerky motions and abnormal facial expressions, with the eventual loss of use of their limbs. Dementia, which is a loss of memory over time, sudden aggression, and development of alcoholism, are some of the many cognitive effects a person with Huntington’s Chorea will suffer (Wyndbrandt, 171). Since the symptoms of HD are so severe and do not show until adulthood, and the disease is acquired at conception, it is hard to discover a positive diagnosis of Huntington’s Chorea before it is too late. Although the possibility of pre-symptomatic testing is available, few choose to do so, becaus... ... middle of paper ... ...a cure, drugs may alleviate some of the symptoms associated with the jerky movements.
This disease doesn’t only make you lose your memory but it also affects thinking, language, behavior, and the tasks of daily life. Having other diseases and other things wrong with you can make Alzheimer’s worse. Signs and Symptoms Some signs of Alzheimer’s disease is hard to detect. Not all memory loss and misplacing of things is Alzheimer related, which is why it is hard to detect. When it is noticed that someone is experiencing signs of Alzheimer’s, the person should see the doctor if it has been going on for a long time.
