Vascular Dementia can occur after a person has a stroke due to major blood vessels being blocked. iii. It also causes your thinking ability to decline by not allowing vital oxygen and nutrients to your brain cells. iv. In an article by Alzheimer’s Association it mentions that many experts who study this type like to call it “Vascular Cognitive Impairment” because it better explains the idea that your vascular thinking skills can change and it can either be small or serve.
Retrograde amnesia is the inability to remember past events and recall memories before the amnesia. It is impossible for patients to recall memories, but they can make new memories,starting from the trauma. The condition is usually the result of a head trauma, stroke, or alcohol intoxication. People lose all basic concepts;what time is, what love is, to read, to write, etc. The most important role here plays the hippocampus located in the central lobe.
They join together at the circle of willis at the base of the brain. Smaller arteries leave the circle and branch out to supply brain cells with oxygen and nutrients.Artery junction points may become weak causing a ballooning of the blood vessel wall to potentially form a small sac or aneurysm.Cerebral aneurysms are common but most are asymptomatic and are found incidentally at autopsy. Causes of Brain Aneurysm: Aneurysms have a variety of causes including high blood pressure and atherosclerosis, trauma, heredity and abnormal blood flow at the junction where arteries come together.There are other rare causes of aneurysms. Mycotic aneurysms are caused by infections of the artery wall. Tumors and trauma can also cause aneurysms to form.
Some of these failures occur over time, while others are affected by other people. Four common memory failures are transience, absentmindedness, blocking, and memory misattribution. Transience is when a memory is forgotten over time. Forgetting a memory occurs drastically at first and then tapers off. Transience is thought to occur because either the memory isn’t completely encoded or because a person hasn’t thought about the memory in a while.
A possible reason for this sense of familiarity could be due to slight memory traces that were left behind due to the insignificance of the memory. An analogy for this is when you erase a program off of a computer, if the program played a role in other systems, you may notice that the system runs differently and might trigger a reminder that you need this program to proceed. Due to the erasing of their memories of each other neither person is the same as they were before the procedure once they are given the information that they had each other deleted. the possible run off of this information could cause an emotional pain and confusion as to why they would do such a
These blood vessels usually nourish the retina. These blood vessels get blocked which causes irregular new blood vessels to form. Bleeding into the vitreous gel may occur due to these new blood vessels being weak. Retinal detachment may also occur because of these new blood vessels pulling on the retina. Diabetic retinopathy is a major cause of visual impairment in middle aged people and visual loss in older people.
Some of the reasons are very serious, such as CTE which is a brain disease caused by rapid hits to the brain, this has lifetime affects and changes you in many ways, in worst cases this can even cause death. Although that is one of the worst things that can happen there is still many others like concussions which last long, Alzheimer’s disease, and little things like depression and headaches all connecting to lifetime affects. The kids that don’t get these
It shows symptoms of loss of motor control, pain and paraesthesia. When there is an inflammation in the white matter or gray matter region of the spinal cord or connecting with brain results myelitis. In myelitis, paralysis and sensory loss can occur due to the damage caused in myelination of the axon. Anterior spinal artery syndrome is a condition that arouse when the blood carrying artery is interrupted. It is common syndrome with symptoms of loss of sensory and motor sensation due to injury.
The Effects of Amnesia In the movies and the novels, we keep exposed to the amnesia themed storylines. As we learn from them, the amnesia can be caused by a head trauma, traumatic events, or physical deficiencies. However, few people understand there are various kinds and symptoms of the amnesia. The aim of this paper is to grasp the effects of amnesia for particular types. The three of symptoms will be mentioned in this paper, which are the impaired ability to learn new information, impaired ability to recall past events and previously familiar information, and inability to recollect the whole truth.
If you don’t already know what Alzheimer's is, it’s a disease that results in memory loss and even confusion, due to the loss of connections between nerve cells in the brain and the death of these nerve cells. APOE is actually one of the many genes that can directly influence your chances of getting Alzheimer’s. There are actually three types of the APOE gene: APOE2, APOE3, and APOE4. APOE4 is actually one of the types that increase your chances for Alzheimer’s and lowers the actual age of onset. When testing for Alzheimer’s, it's not all that different than if you were doing it with a different disease.
These type of dementia occurs about; this occurs due to the short-term memory loss. The other problem will be visual-spatial areas, reasoning, judgement and insight. Hippocampus is the region where it gets affected by Alzheimer’s disease, not only that there will be
A concussion is a tramatic brain injury that alters the way your brain function. Although the effects are usually temporary the effects can be delayed for hours or days and can last days to months. The effects include: headaches, and problems with concentration, memory loss, balance and coordination. Concussions are usually caused caused by a blow to the head or neck or upper part of the body. The cause of a concussion can be from a contact sport, a car accident, or even a kid falling on a playground.
He is unable to retain new memories; he is also unable to unearth past memories to his consciousness as well. The cause for Wearing’s amnesia is viral encephalitis, from the herpes simplex. If this virus travels to the brain it can cause swelling which leads to the brain crushing against the skull. The encephalitis affected various parts of the brain which includes the temporal lobes, the left frontal lobe, and the occipito- parietal lobe. The hippocampus, which is found in the temporal lobe, is completely destroyed affecting the function of memory.
According to a site that specializes in providing information about dementia and Alzheimer’s disease, states that “Dementia is a general term for loss of memory and other mental abilities severe enough to interfere with daily life. It is caused by physical changes in the brain.” (Alzheimer’s Association) Whereas Alzheimer’s is a “Type of dementia that causes problems with memory, thinking and behavior.” (Alzheimer’s Association) Generally speaking, one could imagine
Dementia is often incorrectly referred to as "senility" or "senile dementia," which reflects the formerly widespread but incorrect belief that serious mental decline is a normal part of aging. The condition is progressive and worsens over time; in the later stages, people with dementia become unable to carry out everyday activities and find it difficult to convey their thoughts and feelings. As the symptoms become more profound, they
