Parkinsonism

Parkinson’s disease (PD) is the most common neurodegenerative cause of parkinsonism, a clinical syndrome characterized by lesions in the basal ganglia, predominantly in the substantia nigra.
As a rule, PD begins between the ages of 40 and 70 years, with peak age onset in the seventh decade. The prevalence of PD is approximately 160 cases per 100,000 population, and the incidence is about 20 cases per 100,000 population. The pathological changes of PD may appear as early as three decades before the appearance of clinical signs. The cause of PD is probably multi factorial, with contributions from hereditary predisposition, environmental toxins, and aging.

 Symptoms can take years to develop, and most people live for many years with
the disease. The symptoms caused by Parkinson’s include an ongoing loss of  motor
control (resting tremors, stiffness, slow movement, postural instability) as well as a
wide range of non-motor symptoms (such as depression, loss of sense of smell, gastric problems and cognitive changes).
Parkinson's disease can cause varying and progressive symptoms throughout its course. Some of the most common symptoms associated with the disease include:

  • difficulty showing facial expressions
  • muscle stiffness
  • slowed, affected movements
  • speech changes
  • tremor, especially of one hand

A person with Parkinsonism may have some, but not all, of the symptoms listed above. This is because they also have an additional disorder that affects the brain's functioning.

For example, people with Parkinsonism often do not have the hand tremor that affects many people with Parkinson's disease.

Other symptoms associated with Parkinsonism include:

  • dementia
  • issues with the autonomic nervous system, such as problems with controlled movements or spasms
  • early problems with balance
  • rapid onset and progression of symptoms
Treatment should always be advised by an expert and a qualified medical practitioner.

Alzheimer's Disease

Alzheimer's disease is a progressive disease that destroys memory and other important mental functions. At first, someone with Alzheimer's disease may notice mild confusion and difficulty remembering. Eventually, people with the disease may even forget important people in their lives and undergo dramatic personality changes.

Alzheimer's disease is the most common cause of dementia — a group of brain disorders that cause the loss of intellectual and social skills. In Alzheimer's disease, the brain cells degenerate and die, causing a steady decline in memory and mental function.
At first, increasing forgetfulness or mild confusion may be the only symptoms of Alzheimer's disease that you notice. But over time, the disease robs you of more of your memory, especially recent memories. The rate at which symptoms worsen varies from person to person.

If you have Alzheimer's, you may be the first to notice that you're having unusual difficulty remembering things and organizing your thoughts. Or you may not recognize that anything is wrong, even when changes are noticeable to your family members, close friends or co-workers.

Everyone has occasional memory lapses. It's normal to lose track of where you put your keys or forget the name of an acquaintance. But the memory loss associated with Alzheimer's disease persists and worsens, affecting your ability to function at work and at home.

       People with Alzheimer's may:


  • Repeat statements and questions over and over, not realizing that they've asked the question before
  • Forget conversations, appointments or events, and not remember them later
  • Routinely misplace possessions, often putting them in illogical locations
  • Get lost in familiar places
  • Eventually forget the names of family members and everyday objects
  • Have trouble finding the right words to identify objects, express thoughts or take part in conversations


Brain changes that occur in Alzheimer's disease can affect the way you act and how you feel. People with Alzheimer's may experience:
  • Depression
  • Apathy
  • Social withdrawal
  • Mood swings
  • Distrust in others
  • Irritability and aggressiveness
  • Changes in sleeping habits
  • Wandering
  • Loss of inhibitions
  • Delusions, such as believing something has been stolen
  • Many important skills are not lost until very late in the disease. These include the ability to read, dance and sing, enjoy old music, engage in crafts and hobbies, tell stories, and reminisce.
  This Disorder is progressive and takes time to show it's Symptoms.

Anorexia Nervosa


 An eating disorder characterized by an abnormally low body weight, an intense fear of gaining weight and a distorted perception of weight.To prevent weight gain or to continue losing weight, people with anorexia usually severely restrict the amount of food they eat. They may control calorie intake by vomiting after eating or by misusing laxatives, diet aids, diuretics or enemas. They may also try to lose weight by exercising excessively. No matter how much weight is lost, the person continues to fear weight gain.


  The physical signs and symptoms of anorexia nervosa are related to starvation. Anorexia also includes emotional and behavioral issues involving an unrealistic perception of body weight and an extremely strong fear of gaining weight or becoming fat
.
Physical signs and symptoms of anorexia may include:
  • Extreme weight loss or not making expected developmental weight gains
  • Thin appearance
  • Abnormal blood counts
  • Fatigue
  • Insomnia
  • Dizziness or fainting
  • Bluish discoloration of the fingers
  • Hair that thins, breaks or falls out
  • Soft, downy hair covering the body
  • Absence of menstruation
  • Constipation and abdominal pain
  • Dry or yellowish skin
  • Intolerance of cold
  • Irregular heart rhythms
  • Low blood pressure
  • Dehydration
  • Swelling of arms or legs
  • Eroded teeth and calluses on the knuckles from induced vomiting

   There is no guaranteed way to prevent this but the treatment regime can be designed as follows.

Diabetes


  Diabetes, a metabolic disorder, in which there is a disturbance in the glucose metabolism in  our body.Glucose is vital to your health because it's an important source of energy for the cells that make up our muscles and tissues. It's also our brain's main source of fuel
  The underlying cause of diabetes varies by type. But, no matter what type of diabetes you have, it can lead to excess sugar in your blood. Too much sugar in your blood can lead to serious health problems.Chronic diabetes conditions include type 1 diabetes and type 2 diabetes.
      Diabetes symptoms vary depending on how much your blood sugar is elevated. Some people, especially those with prediabetes or type 2 diabetes, may not experience symptoms initially. In type 1 diabetes, symptoms tend to come on quickly and be more severe.

Some of the signs and symptoms of type 1 and type 2 diabetes are:

  • Increased thirst
  • Frequent urination
  • Extreme hunger
  • Unexplained weight loss
  • Presence of ketones in the urine (ketones are a byproduct of the breakdown of muscle and fat that happens when there's not enough available insulin)
  • Fatigue
  • Irritability
  • Blurred vision
  • Slow-healing sores
  • Frequent infections, such as gums or skin infections and vaginal infections

To understand diabetes, first you must understand how glucose is normally processed in the body.

How insulin works
Insulin is a hormone that comes from a gland situated behind and below the stomach (pancreas).

  • The pancreas secretes insulin into the bloodstream.
  • The insulin circulates, enabling sugar to enter your cells.
  • Insulin lowers the amount of sugar in your bloodstream.
  • As your blood sugar level drops, so does the secretion of insulin from your pancreas.

The picture shown below, in my opinion is the most comprehensive way to sum up this disorder and it's prevention.

Diarrhea

  Diarrhea can be simply explained as lose, watery, and frequent movement of the bowel and stool.
In most cases, diarrhea lasts a couple of days. But when diarrhea lasts for weeks, it can indicate a serious disorder, such as a persistent infection, inflammatory bowel disease, or a less serious condition, such as irritable bowel syndrome
 As for the symptoms, these can be stated simply as:
  • Loose, watery stools
  • Abdominal cramps
  • Abdominal pain
  • Fever
  • Blood in the stool
  • Bloating
  • Nausea
  • Urgent need to have a bowel movement
  If your diarrhea persists for more than two days with severe pain then you should consult your doctor, either wise it may lead to dehydration and other complications which may be life threatening.

A number of diseases and conditions can cause diarrhea, including:
   Viruses. Viruses that can cause diarrhea include Norwalk virus, cytomegalovirus and viral hepatitis. Rotavirus is a common cause of acute childhood diarrhea.
   Bacteria and parasites. Contaminated food or water can transmit bacteria and parasites to your body. 
   Medications. Many medications, such as antibiotics, can cause diarrhea. Antibiotics destroy both good and bad bacteria, which can disturb the natural balance of bacteria in your intestines. This is a major reason why antibiotics should be taken carefully and by the prescription of a doctor as self medication is always harmful.
  If your diarrhea is not controlled it may lead to dehydration and the symptoms of dehydration are as follows:
  • Excessive thirst
  • Dry mouth or skin
  • Little or no urination
  • Weakness, dizziness or lightheadedness
  • Fatigue
  • Dark-colored urine
In infants diarrhea presents with the following symptoms:
  • Not having a wet diaper in three or more hours
  • Dry mouth and tongue
  • Fever above 102 F (39 C)
  • Crying without tears
  • Drowsiness, unresponsiveness or irritability
  • Sunken appearance to the abdomen, eyes or cheeks
  By taking simple steps we can easily prevent diarrhea and these simple steps are:
  • Wash your hands frequently
  • Use sanitizer regularly
  • Vaccination
  • AND WATCH WHAT YOU EAT
These foods can help control diarrhea

Coronary Artery Disease

    Coronary artery disease develops when the major blood vessels that supply your heart with blood, oxygen and nutrients (coronary arteries) become damaged or diseased. Cholesterol-containing deposits (plaque) in your arteries and inflammation are usually to blame for coronary artery disease.


   When plaque builds up, it narrows your coronary arteries, decreasing blood flow to your heart. Eventually, the decreased blood flow may cause chest pain (angina), shortness of breath, or other coronary artery disease signs and symptoms. A complete blockage can cause a heart attack.

   Because coronary artery disease often develops over decades, you might not notice a problem until you have a significant blockage or a heart attack. But there's plenty you can do to prevent and treat coronary artery disease.
   
   If your coronary arteries narrow, they can't supply enough oxygen-rich blood to your heart — especially when it's beating hard, such as during exercise. 
  • Chest pain (Angina)
  • Shortness of breath
These ultimately leading to a heart attack.

   The causative agents or predisposing factors are:
  • Smoking
  • High blood pressure
  • High cholesterol
  • Diabetes or insulin resistance
  • Sedentary lifestyle
  • High stress
  • Diabetes
  • Unhealthy diet


   The preventive measures are easy to take and prevention is always better than treatment.
The same lifestyle habits that can help treat coronary artery disease can also help prevent it from developing in the first place. Leading a healthy lifestyle can help keep your arteries strong and clear of plaque. 
   To improve your heart health, you can:
  • Quit smoking
  • Control conditions such as high blood pressure, high cholesterol and diabetes
  • Stay physically active
  • Eat a low-fat, low-salt diet that's rich in fruits, vegetables and whole grains
  • Maintain a healthy weight
  • Reduce and manage stress

Stroke

   Stroke, normally referred to as the brain stroke, is a medical emergency and occurs when the blood supply to the brain is blocked. Today i shall focus on the signs and symptoms of this condition so you can think "FAST" and act "FAST".
   Nearly 800,000 people have a stroke each year and it is the fifth leading cause of death in the world.
A stroke occurs when the supply of blood to the brain is either interrupted or reduced. When this happens, the brain does not get enough oxygen or nutrients, and brain cells start to die.In the U.S., approximately 40 percent of people who die from stroke are male, with 60 percent of deaths occurring in females.According to the American Heart Association (AHA), compared with Caucasian people, African-Americans have nearly twice the risk of a first-time stroke and a much higher risk of death from stroke.

    I stressed on the word "FAST" so i could hammer in the symptoms by the above depicted diagram.

   A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel (hemorrhagic stroke). Some people may experience only a temporary disruption of blood flow to the brain (transient ischemic attack, or TIA) that doesn't cause permanent damage.
Ischemic stroke:
About 80 percent of strokes are ischemic strokes. Ischemic strokes occur when the arteries to your brain become narrowed or blocked, causing severely reduced blood flow (ischemia). The most common ischemic strokes include:

Thrombotic stroke:
A thrombotic stroke occurs when a blood clot (thrombus) forms in one of the arteries that supply blood to your brain. A clot may be caused by fatty deposits (plaque) that build up in arteries and cause reduced blood flow (atherosclerosis) or other artery conditions.
Embolic stroke. An embolic stroke occurs when a blood clot or other debris forms away from your brain — commonly in your heart — and is swept through your bloodstream to lodge in narrower brain arteries. This type of blood clot is called an embolus.
Hemorrhagic stroke:
Hemorrhagic stroke occurs when a blood vessel in your brain leaks or ruptures. Brain hemorrhages can result from many conditions that affect your blood vessels. These include:



Many factors can increase your stroke risk. Some factors can also increase your chances of having a heart attack. Potentially treatable stroke risk factors include:

Lifestyle risk factors:

  • Being overweight or obese
  • Physical inactivity
  • Heavy or binge drinking
  • Use of illicit drugs such as cocaine and methamphetamines

Medical risk factors:

  • Blood pressure readings higher than 120/80 millimeters of mercury (mm Hg)
  • Cigarette smoking or exposure to secondhand smoke
  • High cholesterol
  • Diabetes
  • Obstructive sleep apnea
  • Cardiovascular disease, including heart failure, heart defects, heart infection or abnormal heart rhythm
  • Personal or family history of stroke, heart attack or transient ischemic attack.

Other factors associated with a higher risk of stroke include:


  • Age —People age 55 or older have a higher risk of stroke than do younger people.
  • Race — African-Americans have a higher risk of stroke than do people of other races.
  • Sex — Men have a higher risk of stroke than women. Women are usually older when they have strokes, and they're more likely to die of strokes than are men.
  • Hormones — use of birth control pills or hormone therapies that include estrogen, as well as increased estrogen levels from pregnancy and childbirth.

   Knowing your stroke risk factors, following your doctor's recommendations and adopting a healthy lifestyle are the best steps you can take to prevent a stroke. If you've had a stroke or a transient ischemic attack (TIA), these measures might help prevent another stroke. The follow-up care you receive in the hospital and afterward also may play a role as well.Many stroke prevention strategies are the same as strategies to prevent heart disease. In general, healthy lifestyle recommendations include:
  • Controlling high blood pressure (hypertension). 
  • Exercising, managing stress, maintaining a healthy weight 
  • Lowering the amount of cholesterol and saturated fat in your diet. Eating less cholesterol and fat, especially saturated fat and trans fats, may reduce the plaque in your arteries.
  • Quitting tobacco use. Smoking raises the risk of stroke for smokers and nonsmokers exposed to secondhand smoke.
  • Controlling diabetes. You can manage diabetes with diet, exercise, weight control and medication.
  • Maintaining a healthy weight. Being overweight contributes to other stroke risk factors, such as high blood pressure, cardiovascular disease and diabetes. Losing as little as 10 pounds may lower your blood pressure and improve your cholesterol levels.
  • Eating a diet rich in fruits and vegetables. A diet containing five or more daily servings of fruits or vegetables may reduce your risk of stroke. Following the Mediterranean diet, which emphasizes olive oil, fruit, nuts, vegetables and whole grains, may be helpful.
  • Exercising regularly. Aerobic or "cardio" exercise reduces your risk of stroke in many ways.
  • Treating obstructive sleep apnea.
  • Avoiding illegal drugs. Certain street drugs, such as cocaine and methamphetamines, are established risk factors for a TIA or a stroke. Cocaine reduces blood flow and can narrow the arteries.
