Dementia is a chronic brain disease associated with gradual decline in the mental ability to think, reason, judge, communicate effectively and changes in their mood or behavior all these symptoms reduces a person’s ability to carry out everyday activities. Alzheimer’s is the most common type of dementia.
Dementia is one of the most common brain diseases that affect many people around the world; researchers are finding new ways every now and then, to reduce the risk of dementia disease. Dementia affects the person when the brain is damaged by diseases, such as Alzheimer’s disease or a series of strokes. Alzheimer’s disease is considered to be one of the most common causes of dementia, but there are also other brain disorders that can lead to dementia.
Studies have shown that with certain lifestyle changes that can help boost brain health you may decrease the signs of dementia disease or at least slow down the process or even reverse, the process of degeneration of brain functions that leads to dementia disease-a chronic and neuro degenerative disorder that leads to gradual memory loss and cognitive decline; as it progresses it leads to complete brain degeneration.
Signs of dementia
- memory loss
- mental decline
- inability to speak
- difficulty understanding language
- inability to recognize common things
- personality changes
- mood swings
- Inappropriate behavior
- getting lost
- unsteady walking
- difficulty in understanding visual images
- difficulty planning and organizing events
- disturbed sleep pattern
- trouble judging distance
- difficulty in recognizing colors,
- staying away from social life
If you or your near one has some of the above mentioned dementia symptoms, see a doctor immediately and get proper treatment.
Causes of dementia disease
Dementia occurs when nerve cells in the brain are destroyed, which can occur in different locations of the brain. The affects of dementia depends upon the area of the brain affected. Dementia’s can also be caused as result of reaction to medications or vitamin deficiencies, but such type of dementia is easily improved with proper treatment.
Types of dementia’s that is not curable
- Alzheimer’s disease– is a chronic and neuro degenerative disorder that progresses slowly overtime. It is the most common cause of dementia. Increasing age also puts the person at risk for developing Alzheimer’s disease. It cannot be ruled out that chronic disrupted sleep during later age may increase the risk of Alzheimer’s later in life. Lack of sleep has been linked to cognitive dysfunction, and Alzheimer’s disease .During sleep the waste-draining system called glymphatic system is many more times active than while awake, during the elimination process that takes place around brain cells, cerebrospinal fluid flows through the spaces between neurons, flushing proteins and other toxins into the circulatory system and away. This process of cleaning waste, discards away proteins called amyloidal-beta, which pile up into plaques that damage nearby neurons and can bring about changes in the brain that may be lead to Alzheimer’s disease. The brains of people with Alzheimer’s disease are dotted with such plaques. According to studies it was due to excessive production of amyloid beta that causes sleep deprivation that leads to an increased risk of Alzheimer’s.
- Some studies believe Alzheimer’s disease is related to genetics. Children of affected parents have higher chances of inheriting their genetic mutation, and those people with affected close relatives also have risk of developing Alzheimer’s disease.
- Vascular dementia – vascular dementia is associated with problems of circulation of blood to the brain, it is the second most common cause of dementia after Alzheimer’s disease. This type of dementia affects people when the blood vessels that supply blood to the brain are damaged due to reasons such as stroke. Unfortunately, vascular dementia cannot be reversed but your doctor may prescribe medicines to keep a check on high blood pressure, high cholesterol, heart disease, blood clots, and diabetes so as to prevent stroke.
- Lewy body dementia – is a progressive disease that is it gradually occurs and worsens over time. Lewy bodies are abnormal protein clumps that accumulate in the brains of people affected with lewy body dementia, Alzheimer’s disease and Parkinson’s disease and cause severe damage to certain parts of the brain that makes the person incapable in many areas.
- Mixed dementia – people above the age 80 years may show the symptoms of mixed dementia that is a combination of Alzheimer’s disease, vascular dementia and Lewy body dementia.
Risk factors for developing dementia
- Heredity – people whose family members or close relatives have history of dementia, then such people are at a greater risk of developing this condition.
- Age –dementia symptoms are most commonly found in people above the age of 65 years. However, dementia can occur in early age also.
- Cognitive impairment – people having impaired cognitive skills are also at risk for developing dementia.
- Sleep disorders- People suffering from sleep disorders are likely to develop dementia, especially those who snore where they frequently stop breathing.
- Depression– people under the spell of severe depression might also have the risk for dementia.
- Diabetes-people suffering from uncontrolled diabetes are at increased risk of dementia.
- Excess alcohol consumption-people who are used to drinking excess alcohol might have a higher risk of dementia.
- Smoking – regular smoking also puts you at risk of developing dementia and blood vessel disorders.
- Other risk factors – people who have high blood pressure (hypertension), high cholesterol levels, and are obese are at great risk for developing dementia.
Preventing dementia disease
You can prevent the dementia with little effort and bringing about changes in your lifestyle that are healthy.
- Take up regular physical exercise such as a cardio exercise, strength training, swimming and walking.
- Take up weight and resistance training exercises that helps increase muscle mass as well boosts brain health.
- Give up smoking and consume alcohol in moderate amount as you age, because these substances may increase your risk of dementia and blood vessel (vascular) conditions.
- Consider doing balance and coordination exercises such as yoga, tai chi and others that can help you stay flexible, very good for improving brain health.
- If you are a sports person, save you head from injuries from sports like soccer, boxing, and football that may put you at risk for Alzheimer’s disease.
- Eat foods that are rich in omega-3 fatty acids and other foods that help maintain brain health. Eat foods that provide you all the important nutrients such as – fruits, vegetables, whole grains and omega-3 fatty acids that can help reduce your risk of developing dementia.
- People who have vitamin D deficiency in their blood are more likely to develop Alzheimer’s disease and other forms of dementia. Get enough vitamin D from sunlight and certain foods that can provide you daily dose of vitamin D.
- Finally be socially active, this will keep your brain and body healthy that may delay the onset of dementia and reduce its symptoms.
