Alzheimer’s disease are usually occur in older age, but the disease isn’t a normal part of aging. Scientists aren’t sure why some people get it and others don’t. But the symptoms that it causes seem to come from two main types of nerve damage:
- Nerve cells get tangles, called neurofibrillary tangles.
- Protein deposits called beta-amyloid plaques build up in the brain.
It’s common to have for a degree of vascular damage in the brain.
These reduce the effectiveness of healthy neurons (nerve cells that carry messages to and from the brain), gradually destroying them. Overtime, this damage may spread to several areas in the brain. The first areas which affects are responsible for memories.
Although that the triggers of Alzheimer’s disease are for several factors known to be increase your risk of developing the condition.
Talk to an expert now:
Age is the single most significant factor in the development of Alzheimer’s disease. The likelihood of developing the condition to doubles every five years after you reach at 65 years of age.
The genes you inherit from the parents can contribute to the risk of developing Alzheimer’s disease, although the actual increase in risk is small if you have a close family member with the condition.
People who have had a severe head injury have been found to be at higher risk of developing Alzheimer’s disease.
Signs and symptoms of Alzheimer’s disease:
The symptoms of Alzheimer’s disease progress slowly over several years.And also these symptoms are confused with some other conditions and it maybe initially put down to the old age.
In some of the cases, infections, medications, strokes or delirium can be responsible for the symptoms that gets worse. Anyone with this Alzheimer’s disease symptoms are rapidly getting worst and that should be seen by the doctor, so these can be managed.
A number of other symptoms may also develop as Alzheimer’s disease progresses, such as:
- Difficulty eating and swallowing (dysphagia)
- Difficulty changing position or moving around without assistance
- Considerable weight loss – although some people eat too much and put on weight
- Unintentional passing of urine (urinary incontinence) or stools (bowel incontinence)
- Gradual loss of speech
- Significant problems with short- and long-term memory
In the severe stages of Alzheimer’s disease, people may need full-time care and assistance with eating, moving and even while using the toilet.
