Check out DeepMind's AlphaFold - and marvel at the complex 3D structure of proteins - at https://alphafold.ebi.ac.uk/

A simple mis-folding in a certain brain protein causes a disease for which we have no cure.

To learn more about this topic, start your googling with these keywords:

- Prion: an abnormal pathogenic agent that is transmissible and able to induce abnormal folding of specific normal cellular proteins called prion proteins that are found most abundantly in the brain.

- Spongiform encephalopathies: a group of rare degenerative brain disorders caused by prions and characterized by tiny holes that give the brain a “spongy” appearance.

- Amyloid: an abnormal aggregate of protein.

- Creutzfeldt-Jakob disease: also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is an invariably fatal degenerative brain disorder. Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. Later symptoms include dementia, involuntary movements, blindness, weakness, and coma. About 70% of people die within a year of diagnosis.
