19
Q

What effects the micro biome of the gut

A

Diet, stress, genes and birth

20

21
Q

What mental disorders does inflammation factors implicate in

A

SZ, BP, autism, MDD, PTSD, sleep disorder etc.

22
Q

What is inflammation

A

The natural defence response of the immune system against environmental insult

23
Q

How does autism effect the connectivity in the brain

A

Reduction in global connectivity but confessed in activity in local networks

24
Q

How does SZ effect the connectivity in the brain

A

Strength of the functional connectivity decreased, diversity of connections increased

25
Q

How does a traumatic brain injury effect the connectivity in the brain

A

Shearing of white matter tracts, inflammatory responses, disrupted neurotransmitters release

Q

What is cognitive testing

A

Assessing patterns of strengths and weaknesses
