A 34-year-old man is reviewed in the neurology clinic due to increased clumsiness

A 34-year-old man is reviewed in the neurology clinic due to increased clumsiness. His wife notes that he has been dropping things around the house more frequently and losing his balance while walking in his home. His behaviour has also changed with reduced concentration, and he has made inappropriate comments around the house. On close examination, while talking to the patient, the patient appears restless, and his right hand twitches and writhes at unpredictable intervals when he is talking.

Given the likely underlying diagnosis, what is the likely aetiology for the condition?
