As more and more causes of Alzheimer’s disease are learned, the path to possible treatment clears up. Essentially, Alzheimer’s is a disorder of the brain, which does not have a cure in sight so far.
More than 5 million people in the US live with this neurodegenerative disorder. Any medications that are given to them are the ones that help manage the symptoms. Researchers have, however, been on the lookout for understanding Alzheimer’s disease better so that a possible treatment plan can be devised.
The Latest Study Says That Leaky Blood Vessels Are Responsible
A study published in the journal Nature Medicine concluded that leaky capillaries in the brain can be responsible for Alzheimer’s disease. Researchers from the University of Southern California (USC) in Los Angeles conducted this investigation.
In the past, research has extensively held two toxic proteins responsible for the brain ailment. These are the tau and amyloid proteins that trigger and multiply the development of Alzheimer’s.
Findings have learned that the soluble forms of these harmful proteins work to damage the healthy brain cells. This study that included 161 older adults and lasted for five years, however, learned that people with the worst memory issues showed leaky blood vessels.
This was irrespective of the presence of the toxic proteins in the brain. In other words, participants with extreme memory problems had leaky capillaries in their brain whether the toxic proteins were present or not
What Does This Mean?
Head researchers of the study say that the leaking blood vessels suggest that cognitive impairment on a mild level can start from early on. Basically, the blood-brain barrier is a structure that is formed by the cells which make up blood vessels.
In a healthy brain, this barrier is strong and the cells fit together. This prevents the unwanted substances from getting in the brain zone. In certain aging brains, however, the junction between the cells get to get loose.
As a result, the blood vessels commence leaking. In the event of such blood vessels leakage, the vessels fail to provide the required nutrients to the brain cells. Moreover, toxin proteins can also cross over the brain barrier. This reaches a finale of brain damage.
The findings from this study were conclusive and they found a strong association between leaky blood vessels and cognitive impairment. In conclusion, it is best to take care of one’s health and make the needed lifestyle changes.
In this regard, exercise regularly, save your head from traumatic injuries, eat healthily, and maintain an active social circle. Exercise delivers more blood and nutrients to the brain. Similarly, healthy eating ensures that you have brain-friendly foods that fight free radicals, which cause brain damage.
Maintaining a social circle and learning new things, on the other hand, keep your brain stimulated and challenged, respectively. Lastly, research agrees that traumatic brain injury can increase the odds of developing neurodegenerative disorders such as Alzheimer’s. Therefore, take measures to reduce the chances of brain injury.
