Dementia And Genetics

By Jack Morgan


In most cases, people who have been diagnosed with dementia presume that the disease may have possibly been inherited. They then believe that there is a high chance of passing it to their children. There is no need to go by this believe even after many family members with dementia still take it as something that their kin and most of their family members will develop.

This article will talk about early onset dementia. This is a type of this condition that is caused by hereditary and genetics problems. This form of dementia tends to cluster within family members. Because of that reason, this disease is commonly known as familial disease. When you have this disease, you should know that you get the hereditary disease. This early onset dementia is commonly cased by the mutation of some genes. There are several genes involved in this situation, such as Amyloid Precursor Protein Gene (APP), Presenilin Genes 1 and Presenilin Genes 2. These genes mutate in people with this disease.

The dementia disease can only be thought to be inheritable if one of the family members is diagnosed with Huntington's disease. It is good for patient and family members to understand that this case is very rare.

It is rare because Huntington's disease is considered to be 'autosomal dominant'. This scientifically refers to a condition whereby dementia disease can only be inherited if there is an existence of a single gene that is faulty.

In most cases, dementia signals as a signal to Alzheimer's disease. Most Alzheimer's sufferers experience vascular dementia which is one of the forms of dementia associated with occurrence of strokes. There are four genes that have been identified and connected with the development of the disease. Three of them affect younger people while one affects older people. People with these genes resulting from family members with an early onset are highly susceptible to developing the condition in their late ages. However, these genes are rare and are transmitted from the parent to their children on a 50 percent basis. This means probably half of the children in a family could have the condition.

They are several types of early onset dementia problems. All of them are caused by mutated genes in certain families. These diseases can be called as hereditary situation. It means that you are able to get these diseases from your parents. All early onset dementia problems are caused by mutated genes.

The best step people should take is to know about their family history even after understanding that it is not mandatory hereditary. If you have a clue about your family history, you will be in a position to predict what may happen in future. Research done at various institutions has been able to establish if the right family history is analysed, a doctor can be able to inform you about the chances of inheriting or passing it to your children.

This is the answer for people who ask, "Is Dementia Hereditary?". Some dementia problems are caused by hereditary problems. These problems are usually called as early onset dementia. Some other dementia situations are caused by losing brain's function. Therefore, you should talk to your doctors to find the real answer for your dementia.

Family are being called across the world to visit different Dementia centres. As shown above, the autosomal dominant that has to do with mutation could cause dementia disease. If you have any family member who has Huntington's disease or fronto-temporal dementia is good to get involved in the research. There is no need to worry much about inheriting or passing the disease to your children and other family because it has different causes.

Few Things To Know About Dementia Rating Scale

By Jack Morgan


There are many people all over the world who suffer from a condition known as dementia. Dementia is a condition that affects people of older ages in the areas of memory loss, behavior, daily routines, and over all health as a result of the affects that dementia has on the human brain.

When it comes to Dementia rating scales also called Reisberg scale, it entails some stages.

In stage one; there is Dementia and also no Cognitive Decline. This is normally a stage whereby a person is normally functioning well, no loss of memory and he/she is mentally healthy. Stage one is the stage where people are not considered to be having Dementia.

The CDR scale has been commended for its effectiveness in detecting mild impairments. The downside of using the scale is however that it takes time to administer the identified reliance and subjective assessment. The other demerit of the instrument is its relative failure to detect changes over time.

When the patient is being clinically tested for the unique dementia rating scale, the patient will interact with various professionals who will use a variety of determining criteria to figure out how severe the condition is in that particular person. There are a number of tests that the patient can under go in order to have the severity of the condition diagnosed.

Stage four is normally regarded as the early stage .There is concentration difficulty, a clue of recent things are decreased and difficulty in management of finances. There is also withdrawal from the family and friends, due to difficulty in socialization.2 years is the average duration of this stage.

There are other tests that help to get a more in-depth look at the impact that the condition has on the patients. Those tests include the general practitioner's assessment of cognition, the memory impairment screen, the mini-memory state exam, the Montreal cognitive assessment, and the Addenbrookes cognitive assessment.

Stage six is also referred as mid-stage and Decline which is at middle Dementia stage. Extensive assistance is required for daily activities. Names of the close family are forgotten and there is little memory of events which are recent. Speaking ability declines and they can only remember some of the things before getting this problem. Average duration for this stage is 2.5 years.

Stage seven, also known as late-stage.People have got no ability to communicate and assistance is needed in most of the activities. Also there is loss of walking ability.2.5 years is the average duration. So if you had no idea about all this, at least by now you have got something to know. Having this idea in your mind is of great importance for you have known some of the things that you didn't know. You can also take a step and teach others about this problem for them to know the stages and how they should face whenever they experience.

What Dementia Is - Its Causes And Precautions

By Jack Morgan


Have you or a relative or a friend been diagnosed with Dementia? Are you feeling confused or anxious about how precarious and risky it can be? If yes, then let us first understand what is Dementia in real terms. The term "Dementia" describes a group of symptoms that involves physical changes in the brain structure which can basically affect personality, thinking, behavior, emotion and memory. This involves mood changes, loss of memory and problems with communication.

The symptoms of dementia develop when the brain is impaired by various diseases, including Alzheimer's disease which accounts for 70 to 80 percent of the cases and also damage caused by certain small strokes. There are approximately 800000 people with this disease in the UK.

Dementia is also classified as a lifestyle condition that can affect anyone due acquired behavior such as consuming large amount of alcohol and smoking marijuana. Other lifestyle disease that are so much related to dementia due to change of eating habits include; diabetes, high blood pressure, and obesity.

Human mind has different regions and each part is responsible for different functions like movement, memory, judgment etc. In case if brain cells of any particular region gets damaged, that region does not carry out its functions properly.

When should you see the doctor? If you note any signs that may suggest dementia, it is advisable to immediately visit a qualified physician who will perform a confirmatory test. He will then identify the cause and give you the right medication to treat the condition. Some conditions are treatable and the patient can fully recover from dementia while in others such as Alzheimer and Parkinson dementia worsens with time.

The major causes of this disease are firstly, Alzheimer's disease where the brain structure changes ultimately leading to the death of the brain cells. Secondly, Vascular dementia where the oxygen supply to the brain breaks down and the brain cells die. Thirdly, Dementia with Lewy bodies that causes degeneration of brain tissue leading to hallucinations and disorientation. Fourthly, Fronto-temporal dementia where the front part of the brain is damaged causing changes in the behavior of the person.

There are several conditions which produce symptoms similar to this disease for instance, depression, infections and tumors. Therefore it is indispensable that a proper medical diagnosis is done at an early stage. This will in turn ensure that if the person is in a treatable position, then a correct medication can be followed.

There are 7 stages involved in this disease. The first stage has no cognitive impairment with no memory problems. The second stage involves very mild cognitive decline where there are memory lapses. The third stage involves mild cognitive decline causing concentration problems and decline in the ability to plan and organize things. The fourth stage is a moderate cognitive decline with impaired ability to perform. The fifth stage is a moderately severe cognitive decline with immense gaps in memory. The sixth stage is a severe cognitive decline worsening the memory difficulties. The last stage is a very severe cognitive decline where the individual completely loses the ability to respond to the environment.

As we have already seen dementia is a condition that affects the mind and may be attributed to old age, illness or change of lifestyle. The condition can be contained if the cause is identified and treated at an early stage; however this may not be possible if the cause is related to old age.
