Describe the types of dementia and common signs and symptoms

With primary dementia, the patient does not have the symptoms as a result of another disease. Two different types of primary dementia are Alzheimer’s disease and Lewy Body dementia. Alzheimer’s disease is a progressive mental deterioration commonly known as senile that can occur in middle or old age, due to generalized degeneration of the brain. People may experience difficulty thinking and understanding, aggression, agitation, difficulty with self-care and so on. Lewy Body dementia is the second most type of dementia after Alzheimer’s which causes a decline in mental abilities. Symptoms may include poor regulation of

Dementia with Lewy bodies (DLB) is a type of dementia that shares symptoms with both Alzheimer 's disease and Parkinson 's disease. It may account for around 10 per cent of all cases of dementia (Alzheimer’s Society, 2016). Lewy refers to the inflammation or neuro-inflammation of the brain (Surendranathan et al, 2015). Both Parkinson 's disease and dementia with Lewy bodies are age-related diseases, although onset before age 65 years is not uncommon and both diseases are more common in men than in women (Walker et al, 2015).

Fluctuations in cognition, attention or alertness; Problems with movement including tremors, stiffness, slowness and difficulty walking; Visual hallucinations (seeing things that are not present); Sleep disorders, such as acting out one’s dreams while asleep Behavioral and mood symptoms, including depression, apathy, anxiety, agitation, delusions or paranoia; Changes in autonomic body functions, such as blood pressure control, temperature regulation, and bladder and bowel function. The symptoms of LBD are treatable: All medications prescribed for LBD are approved for a course of treatment for symptoms related to other diseases such as Alzheimer’s disease and Parkinson’s disease with dementia and offer symptomatic benefits for cognitive, movement and behavioral problems. (Washington) It is not uncommon, however, for early signs of dementia to go undetected. The Mini Mental Status Exam – a common screening test for cognitive impairment and dementia used by many physicians – is not able to detect cognitive impairment in early DLB. (10 things) Lewy body dementias (LBD) are the second most common form of degenerative dementia. Lewy bodies are misfolded protein deposits found in the brains of individuals with several different disorders including Parkinson’s disease (PD) and dementia with Lewy bodies (DLB); and the autopsy of Mr. Williams, indicated the presence of ‘diffuse Lewy body dementia’ in the brain of Mr. Williams. This is more commonly called ‘diffuse Lewy body disease’ which reflects the biological disease process in the brain. LBD is an umbrella term for dementia associated with the presence of Lewy bodies (abnormal deposits of a protein called alpha-synuclein) in the brain. (Washington) Although with so much intensive research, doctors still have trouble diagnosing patients

Lewy body dementia (LBD) is a common form of progressive dementia that affects approximately 1.4 million Americans today which makes it the second most prevalent form of dementia behind Alzheimer’s. LBD is formed when lewy body proteins grow in the area of the brain that controls thinking, memory and motor movement. Generally, there are two types of brain diseases that are affected by lewy bodies; Parkinson’s disease with dementia and dementia with Lewy bodies. Discovered by famous neurologist Frederic Lewy, lewy body dementia can affect a person’s ability to perform daily task, cause mood changes and sometimes leads to brain tumors and strokes. Lewy bodies are made up of tiny, microscopic proteins called alpha- synuclein. Typically, these

The second most common form of dementia is vascular dementia, which happens when there is a blockage in the blood vessels that is in the vast system of the arteries that feeds the brain. Vascular dementia is known to affect the thinking process and older people are generally more prone to developing this disorder. Vascular Dementia, also known as multi-infarct dementia, occurs when cells in the brain are deprived of oxygen. Mini-strokes, also known as silent strokes, are the cause of partial blockage of the blood vessels. The people that suffer from strokes have a 30% chance of getting dementia within three months of their stroke (Kumral and Özgören, 2017).

Dementia is a disease that has been characterized as a deficiency of permanent memory which leads to a decrease in recent memory that can interfere with the ability to engage in professional and social activities (Hamdy, Hamdy, Hudgins, & Piotrowski, 2014). Even recent studies have shown that dementia is not a part of the normal aging process, it has become a very serious and common condition among the older population. An estimated 35.6 million people, with 7.7 million cases diagnosed each year are affected with dementia according to the World Health Organization (WHO) (Hamdy, Hamdy, Hudgins, & Piotrowski, 2014).

Vascular dementia is a decline in thinking skills caused by conditions that block or reduce blood flow to the brain, depriving brain cells of vital oxygen and nutrients. Conditions that can block blood flow to the brain are generally transient ischemic attacks (TIA’s) or stokes. When these occur, often major brain blood vessels are damaged and blocked causing effects on personality, ways of thinking and problem solving, and generally can coexist with

Alzheimer's is described by "plaques" between the withering cells in the cerebrum and "tangles" inside the phones (both are because of protein variations from the norm). The mind tissue in a man with Alzheimer's has continuously less nerve cells and associations. Dementia with Lewy bodies is a neurodegenerative condition connected to strange structures in the mind. The cerebrum changes include a protein called alpha-synuclein. Blended dementia alludes to a determination of a few sorts happening all at the same time. For example, a man may demonstrate both Alzheimer's ailment and vascular dementia in the meantime. Parkinson's ailment is likewise set apart by the nearness of Lewy bodies. Huntington's ailment is described by particular sorts of uncontrolled developments additionally incorporates

Dementia with Lewy bodies (DLB), when cognitive symptoms appear within a year of movement problems, is a complex and challenging neurodegenerative disorder. (Pervin, Edwards & Lippa, 2016). It is complex because the DLB pathology and its impact on certain brain regions are unclear. The pathology includes Lewy bodies, senile plaques and neurofibrillary tangles. It is challenging because its many core features make it difficult for individuals to perform activities of daily living. The core clinical features comprise of declining and fluctuating cognition, behavioural and psychotic behaviours and spontaneous signs of parkinsonism.

Dementia with Lewy Bodies is a form of Dementia which is shares characteristics with both Alzheimer and Parkinson disease

There are many signs and/or symptoms someone with Alzheimer’s may experience. Symptoms range anywhere from cognitive, behavioral and psychological. As far as cognitive signs go, difficulty thinking and understanding may occur, as well as forgetfulness. Behavior can also be affected and includes agitation, irritability, aggression, and personality

More than 47 million people around the world have dementia. Dementia refers to a deterioration in cognitive function, including memory and comprehension. Alzheimer’s disease is the most common cause of dementia but other conditions can also be responsible. Dementia is usually chronic and progressive, so it has a major impact on people’s lives.

Alzheimer is the most common type of dementia that refers to problems with memory, thinking and behavior typically among people aged 65 and older (Alzheimer’s Association.) Dementia is caused by damage to nerve sells in the brain and as a result, neurons can no long function normally and may die. In Alzheimer’s disease, the impairment of the neurons eventually damages one’s ability to carry out basic everyday activities such as walking and eating. According to the Alzheimer’s Research Foundation, physical exercise can reduce the risk of developing Alzheimer’s by up to 50 percent. After developing cognitive problems, regular exercise will help to slow further deterioration. For example, someone that has developed symptoms should take the stairs instead of the elevators as a way to add more movement into their day. It is imperative to acknowledge symptoms of Alzheimer’s disease sooner rather than later so that a health provider can recommend proper treatment options. These symptoms develop over time and gradually worsen over the years.

It is important to distinguish Alzheimer’s disease from mild cognitive impairment and normal dementia. There is a normal amount of forgetfulness that everyone experiences as their body and brain begin to age. However, the three disorders listed above are not part of the normal aging process. Dementia is a disorder of the mental processes caused by a brain disease or damage. It’s true that the most common form of dementia is because of Alzheimer’s disease, but it is important to note that this is not the only disease or illness that can cause dementia. Symptoms of dementia include, but are not limited to: loss of memory, impaired judgment, loss of communication skills, and disorientation. Many individuals with dementia also experience neuropsychiatric symptoms. In a study conducted by Lyketsos et al. (2002), they found that as many as 75% of the dementia participants
