Just as age reflects onto our skin, vision, and bone density, so does it also show its outcome on our brain. Although brain ageing or shrinking is a normal biological process, when it’s at an accelerated rate, it is a detrimental and a worrying aspect of growing older — as it could lead to Alzheimer’s disease (AD).
When compared to a healthy adult’s brain, an AD patient’s brain shrinks three to four times faster. Additionally, the loss of neurons is much that they lose connections with other neurons and die out. This disrupts processes vital to neurons and their networks, including communication, metabolism, and repair. At first, the disease typically destroys neurons and their connections in parts of the brain involved in memory. Later it affects areas responsible for language and reasoning. This affects judgement, ability to perform routine tasks, impairs language, etc. As Alzheimer’s progresses, more nerve cells damage or die, leading to changes in behavior, such as wandering and agitation. In the final stages of the disease, people may lose the ability to recognize faces and communicate. They are unable to control and manage their bodily functions and are completely dependent on somebody else for everything. A person with Alzheimer‘s, eventually becomes helpless and unresponsive to the outside world.
Why does the brain shrink?
The brain weighs around 14 oz (400g) at birth and grows to 3 lb (1.4 kg) by adolescence, but it starts to shrink from around the age of 20, by as much as 10 to 15% over the rest of your lifetime. In AD patients, the pre-frontal cortex (an area at the front of the frontal lobe) and the hippo campus (located in the medial temporal lobe) shrink at a much accelerated rate (three to four times faster) than in a healthy person. The synaptic connections between certain groups of neurons stop functioning and begin to degenerate. When neurons lose their connections, they cannot function properly, that is, transmitting information from cell to cell, and eventually die. As neuronal injury and death spread through the brain, connections between networks of neurons break down, and affected regions begin to shrink in a process called brain atrophy. By the final stage of Alzheimer’s, damage is widespread, and brain tissue shrinks significantly.
How to protect your brain: The key lies in keeping yourself mentally active throughout your life and supplementing your diet with MWH Nourishtra Omega 3. Where engaging in brain-stimulating activities and constantly learning something new helps keep the brain active, MWH Nourishtra Omega 3, which is rich in DHA, helps communication between nerve cells and delays the normal loss of brain cells.
