“Previous studies suggest that seizures and myoclonus, which are both signs of network hyper-excitability, could predict shortened survival in Alzheimer’s disease,” noted the researchers.
In 2019, Aging Medicine reported on the case of a 63-year-old woman with “rapidly progressive dementia”.
The patient was eventually diagnosed with sporadic Creutzfeldt-Jakob disease – a rare disease that causes brain damage that worsens rapidly over time.
The report stated that “she had gradually become immobile and mute and had developed myoclonic jerks in bilateral upper limbs, which persisted for five to ten minutes at a time”.
