Symptoms Of Moyamoya Syndrome

Cognitive Decline

When a patient has moyamoya syndrome, their brain is slowly starving of oxygen. There will be a slow but marked decline in their cognitive abilities. The brain will begin to die from a lack of blood flow and oxygen. As brain damage becomes more extensive, more cognitive abilities will be impaired.

The exact symptoms of cognitive decline are variable because they depend exclusively on what area of the brain is damaged. If the prefrontal cortex becomes damaged, a person's basic consciousness and thoughts may become impaired. A damaged amygdala will impair a person's ability to process their emotions, which could result in unpredictable mood swings and angry outbursts. If any part of the brain that governs the physical body is affected, the neural decline will cause the body to stop working the way it's meant to.
