- Download a PDF of Genetics of dementia. Many people with dementia are concerned that they have inherited the condition and that they may in turn pass it on to their children. Also, family members of people with dementia are sometimes concerned that they might be more likely to develop dementia themselves.

- 1 Genetic mutation— A permanent change in a gene that can be passed on to children. 2  The rare, early-onset familial form of Alzheimer's disease is associated with mutations in genes on chromosomes 21, 14, and 1. 3  Genetic risk factor— A change in a gene that increases a person's risk of developing a disease.

How Human Genetic Engineering Could Cure Alzheimer's Disease How Human Genetic Engineering Could Cure Alzheimer's Disease. written by: Paul Arnold •edited by: Paul Arnold •updated: 12/13/2009. Alzheimer's disease is a common cause of dementia. Currently there are treatments that slow its progression, but there is no cure.This article looks at Alzheimer's disease stages and how genetic engineering could be used to treat and possibly cure this debilitating condition.slide 1 of 4.lthough science is a long way off from finding a cure, genetic engineering could provide the answers. Alzheimer's disease is caused by a loss of nerve cells. They die and cannot be replaced, and the brain shrinks.

Genetics of Parkinsonâs Disease Genetics of Parkinson’s Disease. This article has been cited by other articles in PMC. Abstract. Fifteen years of genetic research in Parkinson’s disease (PD) have led to the identification of several monogenic forms of the disorder and of numerous genetic risk factors increasing the risk to develop PD.

- Definition of Dementia Due to Huntington's Disease. Dementia due to Huntington's disease is primarily an inherited form of dementia. Symptoms include personality changes, intense mood swings, and severe problems with memory that affect everyday life. Therapy and counseling can help with the symptoms of dementia due to Huntington's disease.

Inheritance and Genetics of Hashimoto's Thyroiditis Inheritance and Genetics of Hashimoto's Thyroiditis. Inheritance of Hashimoto's Thyroiditis: There is some evidence that Hashimotos Thyroiditis can have a hereditary link. If autoimmune diseases run in your family, you are at a higher risk of developing one yourself. (Source: excerpt from Hashimoto's Thyroiditis: NWHIC)

Is Diabetes Genetic Diabetes itself is not hereditary; although the risk factors that a person has are passed down through the genes, therefore making it more likely that the next generation will have it. An estimated 80% of those diagnosed with diabetes each year have at least one family member who already has diabetes.

New Genetic Clues to Cause of Parkinson's June 24, 2011 -- Researchers have identified two new genetic variants linked to Parkinson's disease and say they now know how big a role heredity plays in the neurodegenerative disorder.he exact causes of Parkinson's disease are not known, but researchers now believe that both environmental triggers and genetic influences play a role. Genetic variants have been implicated in the small percentage of cases that occur in people under the age of 50, known as early-onset Parkinson's.

Dementia Most types of dementia are nonreversible (degenerative). Nonreversible means the changes in the brain that are causing the dementia cannot be stopped or turned back. Alzheimer disease is the most common type of dementia. Another common type of dementia is vascular dementia. It is caused by many small strokes. Lewy body disease is a common cause of dementia in the elderly. People with this condition have abnormal protein structures in certain areas of the brain.

Dementia Dementia: Introduction. Dementia is a neurodegenerative condition of the brain in which there is a progressive and permanent loss of cognitive and mental performance. This includes loss of memory and impairment of brain function in such areas as language, intellect, judgement, and behavior.

A to Z List of Neurological Disorders Tay–Sachs disease (also known as GM2 gangliosidosis or hexosaminidase A deficiency) is a rare autosomal recessive genetic disorder. In its most common variant (known as infantile Tay–Sachs disease), it causes a progressive deterioration of nerve cells and of mental and physical abilities that begins around six months of age and usually results in death by the age of four.

Causes of Dementia Causes of Dementia. There are many potential dementia causes. The most common cause is Alzheimer's disease, which is responsible for more than half of all dementia cases. Other common causes of the condition include a brain tumor, brain cancer, hypothyroidism, and vitamin B12 deficiency. Dementia is a descriptive term for a collection of symptoms (such as personality changes, memory problems, and behavioral problems) that can be caused by a number of conditions that affect the brain.

Dementia The risk of dementia increases as a person gets older. Most types of dementia are nonreversible (degenerative). Nonreversible means the changes in the brain that are causing the dementia cannot be stopped or turned back. Alzheimer disease is the most common type of dementia. Another common type of dementia is vascular dementia. It is caused by many small strokes.

Dementia Risk factors for dementia include age, family history, heavy alcohol use, hardening of the arteries, high blood pressure, diabetes, high cholesterol, and smoking. Causes of dementia are factors which lead to damage to neurons.

- CMT is a genetic disease-it is an inherited disease. It is caused by inherited mutated genes that are involved in producing substances (proteins) which affect either the axon or myelin sheath of the peripheral nerve.s CMT is a hereditary disease, people who have close family members with CMT have a higher risk of developing the condition themselves. Understanding how the periphery nerves function is important if you want to have a better appreciation of what causes CMT.

What Causes Dementia? The 5 Leading Origins Neurodegeneration is the most common biological cause of dementia and often leads to Alzheimer’s disease. 1  Neurodegeneration is the process where brain cells (neurons) break down and die. These dying brain cells cause a permanent and progressive decrease in mental and physical function over time.

Caring for a Person With Dementia Dementia is a progressive loss of mental function due to certain diseases that affect the brain. The losses are substantial. Over time, all types of dementia will lead to loss of memory, loss of reasoning and judgment, personality and behavioral changes, physical decline, and death. But the course dementia takes can vary widely from person to person. It's influenced by many factors, including age and other conditions a person may have.

'Memories' pass between generations Behaviour can be affected by events in previous generations which have been passed on through a form of genetic memory, animal studies suggest. Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations.

Genome Study Identifies Chromosome 9 Link to ALS The study therefore describes a major cause of familial ALS in the Finland located on chromosome 9p21. Furthermore, the overlap with the risk haplotype (a combination of DNA sequences) recently also reported for frontotemporal dementia provides further evidence of a shared genetic cause for these two neurodegenerative diseases.

- For types of dementia that involve degeneration of nerve and brain tissue, you can take action to prevent further damage. It's possible to do this by reducing dementia risk factors, such as by managing high blood pressure, high cholesterol, type 1 diabetes and stopping smoking.
