Active Brain and Brain Exercise

A brain is called an active brain when it is involved in the activities that fire or stimulates the neurons. Active brain, also called busy brain is a state of brain in which the neurons are firing continuously or are involved in the activities that fire or stimulate neurons. The main key to active brain is that neurons should be stimulated continuously so that they become habituated to stimulation once the necessity arises. It can be achieved through physical exercise or mental exercise. Mental exercise can also be called brain exercise. Based on the mechanism, brain exercise can be classified into two types:

  • Direct: Brain exercise that directly engages the neurons. For example: mental stimulating games, chess, Sudoku.
  • Indirect: Indirect brain exercise involves physical activity that does not directly engage the neurons. For example jogging, running.

Chess, a good mental exercise

Some games like football, basketball or cricket which requires strategic thinking and planning have direct as well as indirect effects in making the brain active.

Advantages of active brain and brain exercise:

Like we need to do weightlifting regularly if we want to build our triceps and biceps and run regularly to be a sprinter or marathon runner, to be a mental athlete, we need to exercise the brain regularly. Brain exercise has similar effect to our brain as the weightlifting have to our muscles.

Dementia is a collective symptom for the decrease in cognitive capacity. It involves memory loss, poor judgement, challenges in planning or solving problems. Exercising the brain regularly can halt or slow the progress of dementia. It increases the cognitive reserve in the elderly population.

Aging is a physiological process that affects each cell and organ of our body. Every organ tend to slow down with aging and so as our brain and the neurons. The normal brain aging can be further worsened by deposition of deposition of harmful substances leading to brain disease. Memory loss is the most common problem encountered during aging. The problem is neurons are less active or the brain is less active during old age. In a sense, then tend to become lazy and do not fire when needed. These lazy neurons must be activated or we should try to maintain the active neurons. This is possible only through active brain and brain exercise is the key to active brain. If you experience the memory loss, then you need to counteract the memory loss by activating your neurons through memorization of your day-to-day activities at the end of the day. If you make the habit of memorizing, then that will provide your neurons the necessary stimulus to become activated and helps you in halting or stopping memory loss.

Here are some simple tips for making your brain active:

  • Memorizing daily activities at the end of day before sleep.
  • Playing board games like chess, tiger moving.
  • Solving puzzles, crosswords and playing Sudoku.
  • Involving oneself in intellectual activities in society like debate and quiz.
  • Learning new language.
  • Make the habit of reading books.
  • Try to make the habit of critical thinking, multidimensional way of observing things.

There are a lot of ways of making the active brain. The key to the active brain is engaging yourself in the activities that are brain storming. Besides, don’t forget about the diet and exercise. These are equally important for active brain and healthier brain. To sum up, brain exercise is a simple and cost-effective way of achieving brain health. The key to brain exercise is active brain and active body.

Dementia Prevention and Awareness


Dementia is a common problem of the elderly population. There are about 40 million cases of dementia today. Alzheimer’s disease comprises more than half of the cases of dementia.This trend just seems to be unstoppable. According to the Alzheimer’s Disease International, it is set to treble worldwide by 2050 causing a global epidemic. Given that there will be a lot of people suffering from Alzheimer’s disease and dementia, the health care budget will significantly rise. So, effort must be made to reduce the cost of dementia care by raising the dementia awareness and prevention strategies.

There is no established method for the prevention of dementia and Alzheimer’s disease. But a small change in your diet or lifestyle can mean a lot for preventing dementia. New prevention strategies that are being studied are focused on lifestyle and dietary factors. Micronutrients like folic acid, vitamin B12, vitamin D and magnesium are thought  to maintain and improve brain health.The results with turmeric and vitamin B are promising. Fish oil, which contains omega-3 fatty acid is also beneficial for the neurons. Similarly exercise has been shown to be effective in preventing amnesia associated with aging. Playing board games like chess, solving puzzles and cross words provides mental stretching to the brain. Experiments have shown these games to be helpful for the prevention of dementia.

Regular exercise, healthy diet and mental stimulation can also be called the three pillars of brain healthy lifestyle. Exercise increases blood circulation and reduces the cholesterol level. Healthy diet provides energy and prevents the formation of harmful chemicals in the brain. Games like Chess and Sudoku gives you the mental stimulation needed for keeping the brain active. And active brain helps in resisting degeneration of brain cells which is responsible for dementia.

Playing chess, a way of achieving healthier brain

Chess is widely considered as an intellectual game. It requires a lot of visuospatial capability and calculation. Some researchers have even found chess players to be more intelligent than the other, while other have rejected this hypothesis. The purpose of writing this blog is not to argue about this point. What i am trying to tell is chess definitely helps in making your brain healthy. Playing this game during old age prevents the age related cognitive decline and dementia.

What the research tells?

Researchers at Universidad de Laguna, Spain compared the students playing chess and those playing soccer or basketball. Their results showed that students playing chess have improved cognitive and problem solving capacity than the counterparts playing soccer or basketball. The findings of this research correlates well with the results of  functional magnetic resonance imaging(fMRI). Researchers at University of Minnesota, USA reported  bilateral activation of frontal, parietal and occipital areas in fMRI  while playing chess. Its the frontal area of our brain that is involved in problem solving and intelligence.

While there are research favoring the importance of chess in brain development, there are some which denies this idea. By using Tower of London test( A psychological test for executive functioning), German researchers dismissed the idea that chess player has superior planning performance as compared to non chess players. Though they thefind planning performance to be superior in the chess players, there was no difference in the intelligence between the chess players and the non chess players.
So the research divides the opinion regarding the superior planning performance and intelligence in chess player. Further research need to be done before we become sure about the effect of playing chess in brain. But what we should not forget is chess is a brain stimulating game and it has been proved by the brain imaging that it helps in the activation of the brain areas.

What are the benefits of playing chess? 

 Psychological and intelligence test conducted on chess  players dismiss the idea of chess players being intelligent or being more efficient planner or thinker than those who don’t play chess. But there are other studies which tend to differ. Here are some benefits of playing chess as mentioned in the website 

  • Increases the IQ
  • Prevents Alzheimer’s disease
  • Increases creativity and problem solving skills
  • Improves memory,reading skills and concentration
  • Promotes the growth of dendrites in the brain

How often do you need to play chess?

There are no clear studies indicating the frequency and time one need to spend . Playing chess is just like doing meditation or your daily routine training like jogging,swimming or cycling. The more you play, the more your chance of reaping the benefits. Like the exercise training or meditation, its never late to start learning chess

Fearing dementia during old age??Vitamin B might be the solution!!!!

Vitamin B12

Sources of Vitamin B12

Vitamin B12 is a water soluble vitamin which has a wide range of function including DNA synthesis and myelination of neurons. A new research study published by University of Oslo has shown yet another vital role of Vitamin B12 in neurological diseases. People suffering from early stage cognitive impairment called Mild Cognitive impairment(MCI) and impending dementia will benefit from the new discovery.The findings of the research have shown Vitamin B12 to be effective in preventing Alzheimer’s disease, especially in those who have high level of homocysteine in their body. Homocysteine is an amino acid, which is thought to be involved in the formation of neurofibrillary tangles in the neurons, thus disrupting the communication between neurons and giving rise to AD. There is a direct proportional relation between increased blood homocysteine level and the rise in mild cognitive impairment.

An elevated level of homocysteine can be reduced by administering Vitamin B12. It can be administered orally, or via injection. But the dose of Vitamin B12 in these persons must be higher than the normal dietary requirement.

What are the sources of Vitamin B12?

Sources of Vitamin B12: Sea foods like salmon, shrimps, sardines; milk and milk products; eggs,red meat and liver and legumes. Vegetarians must be careful to avoid dietary deficiency of Vitamin B12. It’s advisable for the vegetarians to take Vitamin B12 capsules. Similarly, elderly people and those who consume excessive alcohol might have poor absorption of this vitamin. In these cases, it’s better to check your Vitamin B12 level regularly and take the parenteral (injection) form of Vitamin B12.


Withania Somnifera (Ashwagandha) and its neuroprotective effects

What is Ashwagandha or Withania Somnifera?

Withania Somnifera(WS), also called Ashwagandha in Sanskrit is a herbal plant widely mentioned and used in ayurvedic medicine. In Ayurveda, Ashwagandha is used to enhance mental health and memory and research have proved that it, in fact, enhances memory. Recent studies have also shown that the ashwagandha root have other wide range of therapeutic properties like antistress, immunomodulatory and antioxidant.

Ashwagandha its use in neurodegenerative diseases:

The roots of Ashwagandha extracts have shown to reduce the number of hippocampal degenerating cells significantly in the brains of stressed rodents and were neuroprotective in animal models of Parkinson’s disease.

Studies done in rats at Defense Institute of Physiology and Allied Sciences, India have shown that withania somnifera roots can improve the hypobaric hypoxic induced memory impairment and neuronal degeneration. Likewise, study done in Human neuronal cells at Herbert Wertheim College of Medicine, USA showed that Ashwagandha(Withania Somnifera) benefits in Alzheimer’s disease(AD). It shows neuroprotective effects in AD.

Animal studies have shown that withania somnifera reverses the behavioral deficits, plaque pathology and accumulation of β-amyloid peptides (Aβ) in the brain. The roots of WS reverse the effect of beta amyloid induced toxicity in AD. Accumulation of β-amyloid is known to be one of the major pathogenesis associated with AD. Thus withania somnifera (WS) extracts can be used as an agent for the prevention of AD. β-amyloid and ashwagandha treated cells  showed no reduction in spine density, spine area, spine length and number of spines as compared to untreated control thus showing the protective effect of ashwagandha on spine density. It is the reduction of spine area, spine length and number of spines which are related to neurodegenerative diseases causing decrease in synaptic plasticity and thus compromising learning and memory. Study done at Chonbuk National University, South Korea has shown that WS stimulates the NMDA receptor in hippocampal cells which is the brain area important for learning and memory.

So, Ashwagandha is an important herb and recent studies have shown promising results regarding its medical benefits, nevertheless in neurodegenerative diseases.
