Fatal familial insomnia primarily affects the thalamus, a crucial part of the brain involved in regulating sleep and wakefulness. The degeneration of thalamic neurons disrupts the normal sleep cycle, leading to severe insomnia and a range of neurological symptoms. This condition is caused by a genetic mutation that leads to the accumulation of abnormal prion proteins, ultimately impacting the overall functioning of the central nervous system.
The division of autonomic nervous system (ANS) that is affected by anethesia is parasympathetic nervous system (PNS).3
In cases where the central nervous system is affected, there may be a decrease in intellectual abilities, insomnia, hearing loss or tinnitus (ringing in the ears), and uncontrolled muscle movements

The nervous system is primarily affected by poliovirus, specifically the motor neurons in the spinal cord. This can result in muscle weakness, paralysis, and difficulty breathing.
