Concussions and the Future of Contact Sports

Injuries are the last thing one thinks of on game day but they’re an inevitable part of professional sports and they’re shaping what athletics will look like in the future.

Concussions are one of the biggest threats to professional athletes today. Repeated concussions can lead to memory loss, personality changes, depression, and anxiety. After suffering one concussion a person is more likely to suffer a second one, and the effects become more severe. Multiple concussions can increase the risk of Alzheimer’s, Parkinson’s and CTE.

Chronic traumatic encephalopathy (CTE) is a brain disorder that occurs after repeated head injuries. Symptoms include memory loss, impaired judgment, aggression, depression, and suicidal thoughts. In one famous case, Aaron Hernandez, a young professional football player, committed suicide in prison without knowing he had the disease.

A number of sports have changed their rules to prevent head injuries. The NFL, for instance, has moved kickoffs from the 30-yard line to the 35-yard line to reduce the speed players reach before colliding with each other. The NFL will also now penalize a player who lowers his head to make contact with his helmet against an opponent.

Professional boxing and MMA (mixed martial arts) have outlawed strikes to the back of the head, or ‘rabbit punches’. The weight of fighters’ gloves has also changed over the years to control the damage of punches and protect the hands. Larger boxers generally wear heavier gloves, but it is still unclear how much the weight of gloves mitigates the impact of punches.

As rules and regulations change, the future of contact sports remains unclear. For now, anyone participating in contact sports should wear proper safety gear and maintain industry standards.

Have We Found the True Cause of Alzheimer's?

Alzheimer’s has been a mysterious disease ever since it was discovered. Considered to be a condition that fits into the dementia category, Alzheimer’s disease is characterized by physical changes in the brain that deteriorate brain function, cognitive ability, and memory in a certain pattern. People who are at least 65 years old are most often affected, however, there are also early-onset cases.

The progression of Alzheimer’s happens over decades and since the brain is such a complicated organ, it has been difficult for scientists to study.

The brain of the patient that had the first named case of Alzheimer’s disease was found to have amyloid (protein) plaques and tao tangles (tangles of fibers) within it. These abnormalities have long been considered by medical professionals to be one of the main causes of the disease, however recent studies suggest that the true cause could be another condition that happens initially, and this abnormal tissue growth may be a secondary symptom.

Scientists came out with new research this year that highlights chronic inflammation as one of the possible causes, based on the body’s tendency to kill off cells or change the genetic code within cells when inflamed for a long period of time. Alzheimer’s is considered a genetic disorder, meaning that it is caused by mutated genes. This also means that the disease can be inherited from a family member. Because the gene mutation that chronic inflammation causes can get worse as the body ages, it makes a good parallel to the fact that Alzheimer’s usually sets in at an older age.

Although inflammation seems to be a viable candidate, many studies still need to be conducted to see if anti-inflammatory drugs ease the progression or onset of Alzheimer's and dementia.

Currently, there are studies being conducted to find out if we would be able to use an existing anti-inflammatory drug as a treatment or preventative measure. If one is found to work, it would be more accessible to obtain as well as cheaper for both the patient and developers.

At this point in time Alzheimer’s is incurable and lifelong, however, if we are able to pinpoint the cause of this condition we will be able to prevent the onset of the disease and will be well on our way to finding a cure.

Alzheimer's Disease, a Tragic Future for Our Aging Population

An estimated 82 million people will have dementia by 2030, according to the World Health Organization. By 2050, the number of people with dementia in the U.S. will be double what it is today, and 80% of these individuals will have Alzheimer's Disease.

Alzheimer's is a noncurable condition that causes problems with memory, thinking and behavior. A person can have the beginnings of Alzheimer's for years without any visible symptoms. It progressively worsens over time and never improves.

Most people develop Alzheimer's after age 65, although some people may get Early-Onset Alzheimer's decades earlier. 

The greatest factors in getting Alzheimer's is aging and having Alzheimer's in your family. High blood pressure, high cholesterol, and diabetes also increase the odds. Head injuries and not sleeping regularly contribute to a lesser degree as well.

At first, symptoms may not be very noticeable. Misplaced keys, a lost book, a missed appointment. After all, everyone forgets things on occasion. However, with those suffering from Alzheimer's Disease, memory loss and confusion become more frequent, eventually interfering with daily living. They will also exhibit bouts of unexplained anger, depression and mood swings. Usually, close family and friends are the first to notice that something is not right.

In the long run, a patient suffering from Alzheimer's will need care 24 hours a day. They will not recognize family, will forget basic vocabulary, and not know how to feed themselves or accomplish even the most basic day-to-day tasks without assistance.

The brain of an Alzheimer's patient deteriorates due to the development of a type of plaque in brain cells called beta-amyloid, as well as tangles in nerve cells called tau. 

Treatment is limited, as there are only 5 drugs available that slow the progression of memory loss but do not stop it. Sleep drugs, anti-depressants and other mood enhancing drugs are usually prescribed to deal with common symptoms.

We have no way to cure Alzheimer's, nor to restore parts of the brain that have been lost. 

Luckily, there are many new drugs in development. Researchers are working on drugs to slow the deterioration of brain cells. Some hope to develop drugs that may one day even prevent Alzheimer's altogether. 

If pharmaceutical companies are successful, there may be a much brighter future for the elderly and the world may never reach the 82 million patients currently expected to develop this terrible disease.

A Tragic Family of Diseases - Neurodegenerative Disease

There is a family of diseases with two things in common – they involve the death of nerve cells over time and they have no known cure. They are called neurodegenerative diseases.

Parkinson's, Alzheimer's, ALS (amyotrophic lateral sclerosis), and Huntington's 

are a few of the more universally known ones. What they have in common is the progressive loss of structure, function or  death of nerve cells - called neurons.  Neurons are the building blocks of your brain and spinal cord. The body cannot replace or reproduce them,  so once they are damaged, they are lost.

Drugs and treatments are available to provide palliative care. Some may slow the progression or relieve or minimize symptoms such as shaking or pain. As these diseases progress, often over the course of years, they become debilitating and lead to the eventual end of someone's life.

Sadly, at this time there is no known cure for any of the diseases in this family.

The only hope lies in fully understanding the mechanism of these diseases on the sub-cellular level and the neuron circuitry of our bodies on a system-wide level.

Celebrities have brought light to this terrible and tragic condition to help move research forward.  These include Stephen Hawking, Michael J. Fox, Neil Diamond, Muhammad Ali, and Janet Reno. Many of them have used their celebrity to increase awareness and thereby encourage hope for the future.
