What Happens To The Brain As We Age
Ageing is a natural physiological phenomenon. Any living thing on this universe grows old and as we grow old, numerous changes are expected! The changes are just not limited to the external appearance of humans but also applies to the internal organs!!
Here is a brief note on the changes in the brain as age –
- Mass of the brain – Brain mass shrinks especially the frontal lobe and hippocampus
- Cortical density – the outer ridged surface of the brain thins out thus slowing cognitive function
- White matter – Shrinkage of white matter results in loss of memory
- Neurotransmitter substances – Decreased production of neurotransmitter substances like serotonin, dopamine, norepinephrine results in various neurological disorders
These are the common changes in the brain as we age, these changes are responsible for the age-related neurological changes!!
