Usually, people with this disorder have ataxia, mild–moderate sensorineural hearing loss, narcolepsy, and cataplexy. These symptoms start happening when an affected person is about 30 years old.

Due to the similar signs and symptoms, it can result in a misdiagnosis of depression, as well as adverse effects from inaccurately prescribed medications.Generally, dementia involves a steady and irreversible cognitive decline while pseudodementia-induced symptoms are reversible.
A new study found the biggest risk factors and predictors at 60 for dementia at 80. Neurologists weigh in on the research and share ways to prevent dementia.
This underlying cause is reversible if you quit the meds, but other reversible causes might not be so obvious. Depression or major stress could cause impairment to show up in testing, too, Boyle says.
