UPI reports:
COVID-19 causes loss of sense of smell in some of those infected by not only damaging the tissue in the nasal cavity, but also the area of the brain responsible for controlling the senses, a study published Monday by JAMA Neurology found.
The white matter region of the brain plays a key role in communication between cells in the central nervous system, including those that control the senses, according to the National Library of Medicine.
Several of the patients included in this study also had evidence of damage to the brain similar to what is seen in people with Alzheimer’s disease, the autopsies revealed.
