13 Early Warning Signs & Symptoms of ALS (Amyotrophic Lateral Sclerosis)

12. Cerebral Hypoxia

Cerebral Hypoxia represents another dangerous complication of Amyotrophic Lateral Sclerosis due to the diminished respiratory capacity of patients, especially at night. Cerebral Hypoxia is a condition in which there is a significant reduction in the supply of oxygen to the brain even if there is adequate blood flow.

Symptoms of cerebral Hypoxia include difficulty concentrating and paying attention, memory loss, and diminished coordination. Brain cells are extremely sensitive to oxygen deprivation and can begin to die within a few minutes of even a moderate decrease in the brain’s oxygen supply.

As such, much of the cognitive dysfunction experienced by ALS patients is due to cerebral Hypoxia.
