It is released by one nerve ending also known as synapses, and is picked up by another nerve ending. After a message is sent, enzymes in the brain clean the serotonin out of the synapses. C. Main Idea: Patients with OCD have damaged receptor sites and is blocked to prevent sertonin to function potentially. D. Big Point: As Medline Plus explains, on September 25, 2007, recent data shows, that about 7 millions Americans are diagnose with OCD. About the age of 20 to 30 is when the symptoms are noticed by the abnormalities in the brain.
Rachel Pearson Unit 13: Understanding the Process and Experience of Dementia Unit Code: DEM 301 Unit reference number: J/601/3538 Section 1 - Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome? Dementia syndrome is a group of signs and symptoms, in which cause damage to cells in the brain. The most common causes are neurodegenerative diseases; this includes Alzheimer’s, Vascular, and Frontotemporal, lewy bodied, Creutzfeldt - Jakob disease (CJD) and Huntington disease. With these diseases the brain cells degenerate and die more quickly than the normal ageing process. This leads to the decline of a person’s mental health and sometimes physical abilities.
As many as 5.3 million Americans are living with Alzheimer’s disease. Alzheimer's destroys brain cells, causing memory loss and problems with thinking and behavior severe enough to affect work, lifelong hobbies or social life. Alzheimer’s gets worse over time, and it is fatal. Today it is the seventh-leading cause of death in the United States. Learn more: Warning Signs and Stages of Alzheimer’s Disease.
Parkinson’s disease; the brain changes caused by Parkinson’s disease begin in a region that plays a key role in movement. As the brain changes, the disease will begin to affect mental functions, including memory and the ability to pay attention, make sound judgements and plan steps needed to complete a task. Parkinson’s disease is a fairly common neurological disorder in older adults, estimated to affect nearly 2% of those over 65. Huntington’s disease; this disease is a progressive brain disorder caused by a single defective gene on chromosome 4. Symptoms of the disease include abnormal involuntary movements, a severe decline in thinking and reasoning skills, irritability, depression and mood changes.
Case Study on Stroke Name: Institution: Case Study on Stroke Introduction Stroke, otherwise known as cerebrovascular accident, refers to a group of health conditions that occur as neurologic deficits caused by an abrupt interruption of cerebral blood flow. Put differently, a stroke results from a sudden decrease in the blood flow to the brain. An acute stroke is a term used in describing the initial twenty-four hours following a stroke event. Ischemic strokes, which results from embolisms or thrombosis, constitutes the vast majority of stroke cases (87 percent) while the remaining thirteen percent are hemorrhagic (resulting from aneurysm or the rupture of a blood vessel) (Yew & Cheng, 2009, p. 33). An ischemic stroke is usually characterized by a reduction or obstruction of blood supply to the brain due to blocked blood vessels caused by atherosclerosis or a blood clot.
Which additional clinical manifestation(s) should the nurse expect to find if Nancy's symptoms have been caused by a brain attack (stroke)? (Select all that apply.) A) A carotid bruit. Feedback: CORRECT The carotid artery (artery to the brain) is narrowed in clients with a brain attack (stroke). A bruit is an abnormal sound heard on auscultation resulting from interference with normal blood flow.
Alzheimer’s disease Alzheimer’s disease is the most common form of dementia and accounts for between 50 and 70 per cent of all cases. It is a progressive degenerative illness that attacks the brain. As brain cells shrink or disappear, abnormal material builds up as ‘tangles’ in the centre of the cells and ‘plaques’ form outside the cells. These disrupt messages within the brain, damaging connections between brain cells. The cells eventually die and this means that information cannot be recalled or assimilated.
It is called the FAST test: F= Facial weakness A= Arm weakness S= Speech problems T= test all 3 signs and call 999 2.4 Describe the potential changes that an individual may experience as a result of stroke. Some of the physical changes that occur in the individual after suffering a stroke are psychological, behavioural and emotional changes take place after a stroke are in part caused by the physical damage to the brain. When the brain cell is damaged the sensations and parts of the body controlled by the cells can no longer function
Quality Improvement Project on Bed Alarms and Patient Falls Martine Langley University of Louisiana at Lafayette Every year many older adults sustain a fall with or without injuries. In fact one in every three adults that is 65 years old and older makes up this population according to the Centers for Disease Control and Prevention (CDC). A fall is any event when a person has an unintentional loss of balance that causes unexpected contact with the ground. These falls can be observed or unobserved (Kalisch, Hee Lee, & Tschannen, 2011). Falls in the elderly can cause all kinds of injuries and are responsible for many of the brain injuries older adults.
Stroke is well defined in the medical lexicon as a disruption of the normal blood flow to a brain region, leading to a loss of neurological function. The common symptoms of a stroke, such as memory loss, speech impairment, and movement problems, occur when neurons die due to the lack of blood reaching them (National Stroke Association). It is important, however, to look beyond the causes or symptoms of stroke, and rather focus on the experience of stroke. What does it feel like to have a stroke? Are patients conscious during a stroke?
