Lewy Body Dementia Case Studies

1650 Words7 Pages

Sometimes, dementia may have similar symptoms with other psychiatric diseases; however, medical specialists have developed a complex system to identify this illness. National Institute for Neurologial and Communicative Disorders and Stroke-Alzheimer’s Disease and Related Disorders Association define dementia based on the following criteria: 1) decline in cognitive functioning; 2) low score on the neuropsychological test; 3) neuropsychiatric dysfunction in minimum two cognitive areas; 4) absence of delirium (Zahdi and Ham 59). The first criterion is crucial. In order to obtain the detailed history of decline in the patient’s cognitive functions, the specialists should interview a person who has known the patient for a relatively long time and can share detailed information about the person’s cognitive disabilities and the time they started. Such cognitive dysfunctions may include …show more content…

They include:
Lewy body dementia which is the result of the formation of protein substances called Lewy bodies in the nerve cells. As the disease progresses, its symptoms include the following: sleep-related difficulties, behavioral, cognitive and physical dysfunctions. Lewy body dementia can be subdivided into two types:
1) Dementia with Lewy bodies (DLB) which is hard to diagnose at the early stage as it has no obvious symptoms. As it progresses, the substantia nigra neurons which produce dopamine become damaged or die which causes deterioration of the outer cortex of the brain. Many of the remaining neurons contain Lewy bodies. At the later stage, the symptoms of DLB include poor reasoning, memory loss; possibly, difficulties with movement and problems with attention.
2) Parkinson’s disease dementia (PDD) – a type of DLB diagnosed in patients with Parkinson’s disease. A majority of them later suffer from PDD. The disease negatively affects memory, speaking, reasoning

However, the only aspect the state has control over is the educational related reasons for missed diagnosis. Primary care physicians need access, on a biennial basis, to receive the most up to date information about what changes are “normal” in aging and what is not. As we know,**********There are numerous difficulties for physicians when detecting and managing dementia. Among these difficulties there is patient avoidance, combined with the lack of resources and absence of assessment tools and protocols. All of these difficulties are joined with the unavoidable stigma that encapsulates the disease.

It is a neurodegenerative disease and is caused by certain nerve cells in the brain dying. These particular neurons produce the dopamine neurotransmitter and when they break down, dopamine levels decrease causing abnormal brain activity. “DBS Therapy uses a small, pacemaker-like device implanted under the skin in the chest (not in the brain). That device sends electronic signals through a very thin wire (called a lead) which is placed in the area of the brain that controls movement. These signals block some of the brain messages that cause the distracting and disabling motor symptoms associated with Parkinson's” (Health Central).

Parkinson disease is a degenerative disorder of basal ganglia function that results in variable combination of tremor, rigidity, akinesia/ bradykinesia, and postural changes. The causes of Parkinson disease is unknown, but it is widely believed that most cases are caused by an interaction of environmental and genetic factors. It is a progressive disorder of the nervous system that affects movements. It is a progressive neurodegenerative disease that is one of the most common neurologic disorders of older adults. The disorder is characterized by progressive destruction of the nigrostriatal pathway, with subsequent reduction in striatal concentration of dopamine.

Causes Of Parkinson's Disease

473 Words | 2 Pages

One common disease that affects the nervous system in the human body is Parkinson’s Disease. Parkinson’s is a progressive neurodegenerative disorder that causes neurons in the brain to deteriorate. These neurons, called dopamine neurons, produce a neurotransmitter called dopamine, which regulates and controls movement in the human body, and resides in an area of the brain called the substantia nirga. When the amount of dopamine reduces, neurons are lost; when this happens, the symptoms of Parkinson’s disease make their early visits (Giles).

Parkinson’s disease (PD) is a neurodegenerative brain disease that results in a loss of dopamine producing brain cells responsible for coordinating movement. The exact cause of PD is not known but according to National Parkinson Foundation (NPF) (2015), “most experts agree that the condition is caused by a combination of genetic and environmental factors (chemicals, viruses, injuries)”, with some experts explaining it this way “genes load the gun and environment pulls the trigger” (Environmental Factors and Parkinson’s section, para. 1). The NPF argues that PD is not fatal but disease progresses to serious complications. Signs and symptoms of PD are tremor, rigidity, bradykinesia, or akinesia, and postural instability (Ignatavicius & Workman,

The motor symptoms of Parkinson’s disease takes place by a death from dopamine-generating cells in the substantia nigra, a region of the midbrain; the cause of this cell death is unknown. Early in the course of the disease, the most noticeable symptoms are movement related, including shaking, stiffness, slowness of movement and diificulty with walking & bearing. Later, thinking and behavioral problems may arise, with dementia commonly in the advanced stages of the diseases, whereas depression is the most common psychiatric symptom.
