Status Updates From The Brain Health Puzzle Boo...

Working memory worsening at 30(!)

Positives puzzles - slower rate cognitive ageing, delayed start dementia, tolerate greater level disease before onset
Cognitive activity when motivated and not distracted
No such thing multi-tasking
Hippocampus making episodic memory + upload to cortex for long term storage via anatomical change

Strong connections in pathways from use
Age related cognitive decline vs neurodegeneration (loss of cells)
Positives ageing - crystallised intelligence, decision making on experience, ‘procedural memories’, more emotionally stable
T2DM > insulin resistance in brain (Alzheimer’s), heightened inflammation - microglia overwhelm by amyloid > over-activation microglia
Low brain resilience RF dementia

Positives of ageing - crystallised intelligence, decision making based on experience, procedural memories, more emotionally stable
Being brain just as any other organ - physical activity, diet, sleeping well
Age related cognitive decline - reduction in brain volume, myelin sheets deformation, fewer receptors at synapses (but not loss of nerve cells, that’s neurodegenerative disorder)

Interesting points about variety being the ‘spice’ to brain health - excited to learn about neuro plasticity
