Alzheimer's disease is a neurological problem that is characterised by a cognitive decline and memory loss. It is a type of neurodegenerative dementia. The symptoms of alzheimer's disease include not being able to absorb and retain new information, lack of reasoning and judging, not being able to take on complex tasks, impaired visuospatial abilities, problems in reading, writing and speech, among many others. If a person has at least two of these symptoms in a debilitating manner, then the diagnosis can be made in favour of alzheimer's disease. The main causes of alzheimer's are shrinkage of the brain size and death of the brain cells. The immune system is also said to trigger this neurodegenerative disease. Let us find out what medical science has found so far.

1. Connections: many a times, in alzheimer's disease, the memory and behaviour of the person changes because the brain is unable to make proper neural connections which can lead to memory loss of how a person behaved and the elements that formed the basis of the patient's cognition. Apparently, the immune system behaves in the same way within the brain and blocks the connection. This happens because there is constant communication between the brain and immune system along neurological lines, which is where the disease first emanates.

2. Inflammation: the brain is prone to inflammation or swelling that is not the normal kind. This inflammation happens as a result of the activation of the infection fighting neurotransmitters and the chemical changes that happen in the brain when an infection strikes. The inflammation usually happens in the plaques or clumps which the brain tries to protect. These clumps are made up of a protein called amyloid. The immune system is responsible for creating this inflammation in the brain of the patient.

3. Pattern recognition receptors: many of these receptors work in different manners and cooperate with each other to create a response in the brain. These prrs can be found in the brain plaques, and they develop the signs of danger which further fuels the inflammation in the brain as a matter of protection.

4. Activation of cells linked with the immune system: when the prrs begin to respond, it basically activates the immune system and the cells of the same. This is the basic reaction that causes the changes in brain which then leads to the attachment of the protein to the tissue that is diseased, in which case alzheimer's disease starts. The inflammation that we had spoken about earlier basically happens in the nervous tissue.

It is important to recognise and act on the initial signs of alzheimer's disease before it progresses beyond one's control.

Can the Immune System Trigger Alzheimer's Disease

Did you know that yoga poses help you in achieving greater flexibility rather than develop it? If you are suffering from stiff hamstrings, painful lower back and locked-up hips and tried many yoga poses without any help, then you may not have tried the right poses. When the body is stiff, it feels like you are trapped within your own body. Flexibility exercises can help in alleviating joint stiffness that may have developed due to a wide array of reasons. Here are the main asanas that are great for joint flexibility.

1. Big toe pose or Padangusthasana: This yogic pose can calm the nervous system and relieve stress and anxiety and stimulate your kidney and liver to optimize their functions. With regular practice, your calf muscles and hamstrings would stretch and your thighs would become stronger. If you are suffering from indigestion and insomnia, then big toe pose is a must try and it also helps in alleviating the symptoms of menopause.

2. Bound angle pose or Baddha Konasana: This pose offers a host of benefits that include stimulating your abdominal organs, prostate glands, ovaries, kidneys and bladder. It also stimulates blood and oxygen circulation throughout the body and improves the heart condition. It is a therapeutic treatment for high blood pressure, anxiety, mild depression, fatigue flat feet, asthma and infertility. With consistent practice, you will be able to stretch your knees, groin and inner thigh.

3. Child's pose or Balasana: This resting pose calms the mind and improves digestion to a great extent. It helps in elongation of the lower back by opening up and stretching this part of the body where all the weight is dumped while you sit and work all day long.

4. Cow face pose or Gomukhasana: When performed regularly, this pose helps in deep stretching the hips, thighs, ankles, armpit, shoulders, triceps, chest and deltoid.

It also aids in strengthening the spine and abdominals, and its folded variations are a great way of decompressing lower spine and clearing the hip joint.

Increased flexibility is one of the topmost benefits of yoga that would surely equip you with the freedom of movement and relaxation. However, it is always important to consult an expert before you try these poses, as they can evaluate your medical history and select the ideal yogic postures that would work best for you.

Improving Joint Flexibility Through Yoga

Headaches are common among working people as accumulated stress results in headaches and tiredness. Among the many different causes, strain on the eyes is one of the leading reasons for that annoying headache.

Taking an eye exam is recommended in case you are having headaches. The issues may not always be related to the eyes, but still a thorough eye check up is recommended. Strain in the eye is caused when small muscles present in the eye have to put in more effort than usual. Symptoms include aching, tired eyes with blurred vision and accompanying headaches. Such headaches are caused because of the following reasons:

Astigmatism
The cornea is in abnormal shape and causes people to squint when they want to focus, and this leads to bad headaches.

Hyperopia
This disorder is also called farsightedness. In case of this disorder, the images are focused by the eye behind the retina, and causes blurred vision and strain upon the eyes. Headaches occur as a result.

Presbyopia
This kind of problem occurs when the lens hardens and becomes inflexible with old age. This makes it hard for a person to focus and causes sore eyes along with headaches.

All disorders or conditions of the eyes can be rectified with the use of prescribed spectacles and contact lenses. For people already having glasses, regular eye check up should be carried out. Your power may increase which you are unlikely to notice, so regular check ups are vital.

Other causes
Headaches related to eye strain and eye problem can also develop from other causes. They are:

1. Glaucoma, an eye disease also causes headaches. This disease is characterized by the development of a fluid in the eyes, which in turn causes the internal eye pressure to shoot up. This pressure fluctuation can lead to headaches in many cases of glaucoma.
2. Cataract affected people suffer from headaches as well. Cataracts develop in individuals due to ageing. The lens becomes cloudy, and the vision gets blurred and slowly diminishes. The eye has to give more effort resulting in eye strain and accompanying headaches.

Prevention
In case you are having headaches, and you are not being able to find out the reason behind it, you should have an eye check up. Eyes are very sensitive and added strain to them causes headaches. People who use computers for long hours are affected by headaches due to eye strain. The best prevention is to have an eye examination and switch to glasses or lenses if required.

Headaches are of various kinds and arise from different factors, but eye strain is known to cause a lot of headaches in people who do eye stress involving activities.

Headaches? Get Your Eyes Checked!

The way we sit, walk, bend or stand is hugely dependent on one very vital organ of the human body; the spine. The spinal column provides strength and support to your entire framework. It has nerves, muscles, bones and tendons; all of which enhance proper functioning of your body. The human brain sends signals to the nerves in your spinal cord, a mass of nerve fibers and tissues ensconced within the spine, which further prompts every single part of your body to perform minute and notable actions all the same. A spine injury can, thus impair your health; in many cases it can even turn out to be fatal. Care should be taken to avoid sources of spine shock or injury. If an injury has already been acquired, it should be treated either through exercising or through medical assistance. 

A few postures to reap the benefits of a fit spine:

1. Twist your spine either early in the morning or after a tiring day: Fold one leg while the other leg remains perched on the folded one. If the left leg is folded the left elbow should be rested on your perched right knee and the right palm should be placed on the yoga mat behind your right hip. This posture can be repeated by folding the right leg as well. It increases spine mobility by twisting it to the end of its range sideways. Muscular spine aches can be remedied by following this posture once each day.
  
2. Do not slouch but sit straight: Some people are in the habit of slouching when they sit or stand. This is an absolutely wrong thing to do if your spine health is of any concern to you. Stretch out your shoulder blades and remain erect while standing and the same should be followed while sitting. Bending one's spine, unless it is necessary, can be very harmful.  
    
3. Stretch your spine in three directions: This exercise is a good way to allay the tension your spine has to undergo every day. Sit with folded legs, intertwine your fingers and stretch your arms upward, in front and at the back to expand your spine to the full. 
  
4. The downward doggy posture can relieve back pain: In this yoga posture, one is expected to stretch his or her legs according to the width of the person's back and stoop forward by placing the palms on a yoga mat. Knees and elbows should not bend.

The kidneys are a pair of bean shaped organs responsible for blood filtration. It also eliminates waste products from the body. The kidneys are located in the abdomenal cavity of the body and help in keeping a check on the electrolyte level in the body.

Polycystic kidney disease or PKD is a condition in which a number of cysts grow on the kidneys. The cysts are filled with fluid, and if the number or the size of the cyst increases, it can lead to kidney damage and kidney failure. 5% of kidney failures are caused by PKD. PKD does not affect only the kidneys. It can also cause the cyst to grow on other organs, such as liver, pancreas, ovaries, spleen and large bowel. The brain and the heart can also be affected by PKD. If it reaches the brain, an aneurism is caused. Heart murmurs may occur if PKD affects the heart.

Symptoms: Symptoms are visible for those in the 30 to 40 age group; however, it differs from person to person. Back pain or side pain, enlargement of the abdomen, blood in the urine, high blood pressure, and frequent bladder or kidney infections are some of the common symptoms of PKD.

Diagnosis: An ultrasound is the most dependable, affordable and non-invasive way to diagnose PKD. MRI and CT scans can be used to detect the volume of the cyst. It also helps to determine small cysts which cannot be detected by ultrasound.

Treatment: There is no specific treatment for PKD at present. But certain steps and measures can be taken to slow down the growth of the cyst and to control the symptoms.

Prevention: Keeping a check on blood pressure, use of prescribed antibiotics to treat kidney or bladder infection, restricted use of caffeine, and medications to control pain are some of the treatments for relief and for arresting the growth of the cyst. Research also shows that drinking plenty of water throughout the day can also slow down the growth of the cyst. A diet low in fat and moderate in calories is recommended.

Types: Autosomal dominant kidney disorder is a genetic disorder and is passed on to the child from the parent by dominant inheritance. It is the most common type of PKD. The symptoms are visible after the age of 30 to 40. Infantile or autosomal recessive PKD is a genetic disorder and is inherited by the child from the parent by recessive inheritance. The symptoms are visible during the early months of life or in the womb. It is a rare form of PKD and occurs in 1 out of 25,000 people. Acquired cystic kidney disease occurs due to long-term kidney damage and is linked with kidney failure and dialysis. The bleeding of the cyst causes the bleeding in the urinary system and leads to urine discolouration.
