Dementia is a type of progressive brain disease, used to describe various symptoms of cognitive decline. As such forgetfulness.
It causes a decline in mental function that interferes with one’s daily activities. Among the mental functions affected by dementia are memory losses, thinking processes, language, orientation, judgment, and social behaviour.
Some dementia patients are unable to perform their daily activities. They also will have difficulty solving problems or controlling emotions.
According to the World Health Organization (WHO), there are 47.5 million people with dementia across the world. Each year, the number increases by 7.7 million people. If you have a close family member who has dementia, you are not alone.
People who are older are at a higher risk for dementia. At the same time, over half of the population will not have dementia even at the age of 95.
Some types of dementia are more commonly found in women than in men. People with chronic diseases such as high blood pressure, heart disease, diabetes, and high levels of fat in the blood are at a higher risk of dementia.
Types of dementia
Dementia is further divided into several types and each of them has different causes. Some types of dementia include Alzheimer’s disease, vascular dementia, or dementia with Lewy body. All of these types of dementia produce similar symptoms, but there are some symptoms that refer specifically to that type of dementia.
Alzheimer’s disease. For Alzheimer’s disease, the patient’s brain suffers from atrophy. The number of nerves in the brain and some of the other types of chemicals that are used to perform brain work will decrease. In addition, a plaque will be formed around the brain tissue. The symptoms of the patient get worse as more parts of the brain are involved.
Vascular Dementia. It occurs in 1 out of 5 dementia cases. It is caused by small blood vessels in the brain that will block the blood clots and which causes a stroke. Strokes do not always come with symptoms, but they can also come with other symptoms such as cognitive problems. Brain tissue that does not receive a good supply of blood after a stroke will die and this may cause the function of the brain to decline and dementia will develop over a long period of time.
Dementia with Lewy body. Lewy body dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. It affects chemicals in the brain whose changes. It can lead to problems with one’s movement, behavior and thinking.
Although dementia causes memory loss, not all who suffer memory problems are due to dementia. A memory disorder can also occur when a person is distracted with hectic schedules. Someone who is in the state of stressing too much will often forget. In addition, physical or mental illness can also interfere with a patient’s memory.
Among the long-term effects of dementia is dementia patients may experience severe problems such as limited movement and difficulty in holding urine. At this point, they depend entirely on their guardians. A person diagnosed with dementia can live up to 20 years after being diagnosed.
Some habits such as smoking and consuming alcohol, chronic illness if it is properly monitored can reduce the risk of dementia. You may also train yourself early to learn new hobbies like playing musical instruments, reading, playing puzzles like Sudoku, and any mind-blowing activities.
