Brain fog – poor memory, difficulty thinking clearly etc

Brain fog – poor memory, difficulty thinking clearly etc by Dr Sarah Myhill MB BS

What allows the brain to work quickly and efficiently is its energy supply.

If this is impaired in any way, then the brain will go slow. Initially, the symptoms would be of foggy brain; but if symptoms progress, one will end up with dementia. We all see this in our everyday life, with the effect of alcohol being the best example.

Short-term exposure gives us a deliciously foggy brain – we stop caring, we stop worrying, it alleviates anxiety. However, it also removes one’s drive to do things, one’s ability to remember; it impairs judgement and our ability to think clearly.

Medium-term exposure results in mood-swings and anxiety (only alleviated by more alcohol).

What I mean by brain fog

  • Poor short term memory
  • Difficulty learning new things
  • Poor mental stamina and concentration – there may be difficulty reading a book or following a film story or following a line of argument
  • Difficulty finding the right word
  • Thinking one word, but saying another

Good Energy Supply to the Brain

A normal nerve will pass a nerve impulse in 75 microseconds. The slower the time, the more we “lose it”. Reaction times are slowed with alcohol. If this interval extends to 140 microseconds, one has dementia; longer than that and we go unconscious – as exemplified by the effects of a general anaesthetic.
