Answer:
False.
Step-by-step explanation:
A reduction of oxygen supply to the brain (due to heart attacks or strokes) do not cause organic disorders such as dementia or Parkinson's disease.
Instead, it would cause 'medical shock' - a condition when the body begins to shut down (this is when CPR is used for heart attacks) because red blood cells are unable to get oxygen to vital organs such as the brain, heart and lungs.
