What is dementia?

The word dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life. A person with dementia may also experience changes in their mood or behaviour. Dementia is caused when the brain is damaged by diseases, such as Alzheimer’s disease or a series of strokes. Alzheimer’s disease is the most common cause of dementia but not all dementia is due to Alzheimer’s. The specific symptoms that someone with dementia experiences will depend on the parts of the brain that are damaged and the disease that is causing the dementia. SYMPTOMS Each person is unique and will experience dementia in their own way. The different types of dementia tend to affect people differently, especially in the early stages. How others respond to the person, and how supportive or enabling the person’s surroundings are, also greatly affect how well someone can SYMPROMS (problems with thinking or memory) -day-to-day memorY – difficulty recalling events that happened recently -concentrating, planning or organising – difficulties making decisions, solving problems or carrying out a sequence of tasks (eg cooking a meal) -language – difficulties following a conversation or finding the right word for something -visuospatial skills – problems judging distances (eg on stairs) and seeing objects in three dimensions -orientation – losing track of the day or date, or becoming confused about where they are. As well as these cognitive symptoms, a person with dementia will often have changes in their mood. For example, they may become frustrated or irritable, withdrawn, anxious, easily upset or unusually sad. With some types of dementia, the person may see things that are not really there (visual hallucinations) or believe things that are not true (delusions). Dementia is progressive, which means the symptoms gradually get worse over time. How quickly dementia progresses varies greatly from person to person. As dementia progresses, the person may develop behaviours that seem unusual or out of character. These behaviours may include repetitive questioning, pacing, disturbed sleep patterns or agitation. They can be distressing or challenging for the person and their carer. A person with dementia, especially in the later stages, may have physical symptoms such as muscle weakness or weight loss. Changes in sleep pattern and appetite are also common. What causes dementia? THE MOST COMMON TYPES OF DEMENTIA: Alzheimer’s disease – This is the most common cause of dementia. Brain cells are surrounded by an abnormal protein and their internal structure is also damaged. In time, chemical connections between brain cells are lost and some cells die. Problems with day-to-day memory are often noticed first, but other symptoms may include difficulties with: finding the right words, solving problems, making decisions, or perceiving things in three dimensions. Vascular dementia – If the oxygen supply to the brain is reduced because of narrowing or blockage of blood vessels, some brain cells become damaged or die. This causes vascular dementia. The symptoms can occur either suddenly following one large stroke, or over time through a series of small strokes or damage to small blood vessels deep in the brain. The symptoms of vascular dementia vary and may overlap with those of Alzheimer’s disease. Many people have difficulties with problem-solving or planning, thinking quickly and concentrating. They may also have short periods when they get very confused.

What is difference Between the Right Brain and Left Brain?

You may have heard people describe themselves as strictly "right-brained" or "left-brained," with the left-brainers bragging about their math skills and the right-brainers touting their creativity. That's because the brain is divided down the middle into two hemispheres, with each half performing a fairly distinct set of operations. Much of what is known about brain function is owed to Roger Sperry, whose experiments examined the way the human brain's hemispheres operate both independently and in concert with each other. The two hemispheres communicate information, such as sensory observations, to each other through the thick corpus callosum that connects them. The brain's right hemisphere controls the muscles on the left side of the body, while the left hemisphere controls the muscles on the right side of the human body. When you wink your right eye, that's the left side of your brain at work. Because of this criss-cross wiring, damage to one side of the brain affects the opposite side of the body.

Left and right hemisphere

I am the right brain. I am creativity, a free spirit. I am passion. Yearning, sensuality. I am the sound of roaring laughter. I am taste, the feeling of sand beneath bare feet. I am movement. I am vivid colour, the urge to paint on an empty canvas. I am boundless imagination. Art, poetry. I sense. I feel. I am everything I wanted to be. I am the left brain. I am a scientist, a mathematician. I love the familiar. I categorize. I am accurate, linear, analytical. Strategic, practical, I am always in control. A master of words and language. Realistic, I calculate equations and play with numbers. Order, logic. I know exactly who I am.

All about strokes

WHAT IS A STROKE? A stroke happens when there is some disruption or a blockage to the flow of blood to the brain, or leakage of blood into the brain. This means that blood cannot reach a particular part of the brain, which then becomes damaged. TWO TYPES OF STROKE: Cerebral infarction – blockage of a blood vessel in the brain, this could be caused by a blood clot or fatty clot Cerebral haemorrhage – rupture of a blood vessel in the brain CAUSES OF STROKE -High Blood Pressure (hypertension) -Smoking -Eating a diet high in saturated fat -Using too much salt in food -Being overweight and not taking enough exercise -Alcohol -Diabetes -Heart disease -Family history EFFECTS OF STROKE: Stroke affects everybody in different ways. The effect of a stroke on a person depends on which part of the brain has been affected and how much damage has been caused. Some of the effects of stroke can include: -Weakness down one side of the body. This can create difficulties walking, getting in and out of bed, -getting washed and dressed etc. -Difficulties with speech and swallowing -Inability to think things through clearly, and memory problems -Problems with sight and awareness of objects around you -Changes with bladder and bowel function -Emotional changes -Sudden tiredness CAN BE STROKES BE PREVENT? Yes. You can reduce your chances of having a stroke by: Getting treated for high blood pressure (This is very important. It might involve taking one or more medicines.) Not smoking Being active Controlling your blood sugar if you have diabetes Losing weight if you are overweight Eating lots of fruits, vegetables, and low-fat dairy products, but not a lot of fatty or salty foods Taking your medicines exactly as directed. Medicines that are especially important in preventing strokes include: Blood pressure medicines Medicines to prevent blood clots, such as daily aspirin or warfarin (sold as Coumadin®) Medicines called statins, which lower cholesterol

Human Brain

The human brain is divided into several parts that control movement and sensory function, or how the body moves and feels. This picture of the brain shows some of these areas. When a stroke damages a certain part of the brain, that area may no longer work as well as it did before the stroke. This can cause problems with walking, speaking, seeing or feeling.

The left side, or hemisphere, of the brain controls how the opposite (right side) of the body moves and feels, and is responsible for how well we can figure out problems with science, understanding what we read and what we hear people say, number skills such as adding and subtracting, and reasoning. The right side of the brain controls the movements and feelings on the left side of the body and is in charge of how artistic we are, including musical and creative talents. CLICK TO SEE THE IMAGE:
