Covid-19 Impacts the Brain

Covid-19 Causes Brain Damage

Covid-19 Causes Cognitive Impairment

Covid Causes Alzheimer’s-like Pathology and Accelerates Existing Alzheimer’s Disease

• Covid invades cognitive centers of the brain and induces Alzheimer’s-like neuropathology

(Shen et al., 2022 *preprint doi: 10.1101/2022.01.31.478476)

• Covid is associated with accelerated progression of Alzheimer’s disease


• Covid produces proteins that form cytotoxic aggregates which damage neuronal cells, which parallels Alzheimer’s disease mechanism

(Charnley et al., 2022 doi: 10.1038/s41467-022-30932-1)

• COVID increases the risk of neurodegenerative disorders- Alzheimer’s disease risk is 3.5x increased; Parkinson’s disease risk is 2.6x increased; ischaemic stroke risk is 2.7x increased and intracerebral haemorrhage (bleeding in the brain) risk is 4.8x increased.

(Zarifkar et al., 2022 doi: 10.3389/fneur.2022.904796)

• Risks of cognitive deficit, dementia, psychotic disorders, and epilepsy or seizures are increased for at least 2 years following Covid infection.

(Taquet et al., 2022 doi: 10.1016/S2215-0366(22)00260-7)

• A study of hospitalised Covid patients showed neurodegenerative biomarkers elevated to levels seen in Alzheimer’s Disease dementia.
