Aged brains are prone to neurodegenerative illnesses where the same damages accumulate in lesser numbers. Normal ageing, neurodegeneration, and dementia can overlap with lesions and cognitive impairment.

Does aging result in neuronal degeneration?
Iron is involved in oxygen transport, DNA synthesis, mitochondrial respiration, myelin synthesis, and neurotransmitter

What role does iron play in the brain?
Repeated fresh frozen plasma infusions can reduce brain iron levels. Vitamin E, an iron chelator, or zinc sulphate are used to prevent tissue damage in aceruloplasminemia.

How do you reduce iron accumulation in the brain?
Oxidative stress causes neurons to age and accumulate damaged proteins and mitochondria. This process increases ROS production and/or decreases antioxidant scavengers.

How are neurons affected by age?
Older adults, including those with MCI, Alzheimer's, form new hippocampal neurons. Neurogenesis, the formation of new brain cells, appears to continue into old age, according to a recent NIA-funded study.

Can elderly brains grow new neurons?
Brain iron shortage disrupts neurophysiological systems, compromising physical and cognitive development in a social situation without regular stimulation (e.g., impaired motor sequencing and bi-manual coordination, poor executive function, attention, and memory).
