Valley College Different Types of Dementia Responses


Please comment to each post and ask each one a question. .

Prompt 1: Explain in detail the different types of dementia. 

A few of the different types of dementia include Alzheimer’s disease, frontotemporal dementia, lewy body dementia, and vascular dementia. Alzheimer’s disease is the presence of amyloid plaques and neurofibrillary brain tangles. Symptoms include getting lost, repeating questions, and forgetting simple details. Frontotemporal dementia is an abnormal accumulation of proteins inside neurons of the frontal and temporal lobes. Symptoms include impulsive behaviors, emotional swings, balance issues, and difficulty forming speech. Lewy Body dementia affects the brain’s chemical messengers. Symptoms include the inability to concentrate or focus, insomnia, loss of coordination, and muscle rigidity. Vascular dementia is obstructed blood flow to the brain from blood clots, for example. Symptoms include hallucinations, memory loss, and poor judgment (“Understand different types of dementia,” n.d.). Rowena experienced vascular dementia and had to be put on TPA to clear her blood clots. 

Prompt 2:  Explain in detail the difference between ischemic vs. hemorrhagic stroke.

Ischemic stroke is caused by a lack of blood supply, hence the word ischemia. Hemorrhagic stroke is caused by bleeding into brain tissue (Narayanan, 2023). Ischemic stroke is much more common than hemorrhagic stroke. Sometimes, an ischemic stroke cannot be busted with thrombolytics, and this may result in severe patient conditions. Hemorrhagic stroke includes a ruptured blood vessel in the brain and therefore symptoms include vomiting, seizure, headache, and weakness on one side of the body. Rowena’s dementia is ischemic, as it is caused by a blood clot which means not enough blood was getting to her brain. It did not involved bleeding in her brain. Her daughter was able to detect the signs early and therefore she was rushed to the hospital where the nurses were able to clear the clot with TPA.

2. Prompt 1: A category of neurodegenerative illnesses known as dementia are characterized by memory loss and cognitive deterioration. There are various varieties of dementia, each with its own underlying factors and clinical characteristics. Amyloid plaques and tau tangles build up in the brain in Alzheimer’s disease, the most prevalent type of dementia, which causes progressive cognitive impairment. Vascular dementia is caused by decreased blood supply to the brain, which is frequently a result of little strokes or infarcts harming the brain’s tissue.

Prompt 2: The two main forms of strokes are ischemic and hemorrhagic, each with unique causes and mechanisms. The obstruction or loss of blood flow to a portion of the brain that results in an ischemic stroke is typically brought on by a blood clot (thrombus) or an embolus that has lodged in a brain artery. As a result, the damaged area’s brain cells are deprived of oxygen and nutrients, which causes cell death.

Prompt 3: When given within 3-4.5 hours of the beginning of symptoms, tPA treatment can considerably improve patient outcomes and lessen disability in ischemic stroke patients. However, because to the possibility of brain bleeding (intracranial hemorrhage) caused by tPA, cautious patient selection and attention to treatment recommendations are essential. The length of time since the onset of Rowena’s stroke symptoms, her medical background, and the outcomes of diagnostic testing like brain imaging would all affect whether she was eligible for tPA treatment.

Prompt 4: If she is found to have her kind of dementia, doctors may provide medications to treat the symptoms and halt the disease. Rowena can benefit from having a supportive environment as well as assistance with daily tasks. Her overall health would need to be monitored often, and any underlying issues would need to be managed. To make sure her family and caregivers have the tools and knowledge to take the greatest care of Rowena’s wellbeing, education and support are also essential.
