A 39 year-old male presents to your office accompanied by a family member, who helps provide the history. The patient has had a 1 year history of worsening psychiatric and neurologic issues, including odd movements and memory problems and uncharacteristic apathy.
The patient is on metoprolol for hypertension, and has no other past medical history.
The patient confirms that other family members have had similar symptoms, and some have died at an early age.
On exam, you note motor impersistence, generalized choreiform movements, slightly impaired memory, oculomotor dysfunction, and cognitive slowing.
MRI of the brain is remarkable only for slight atrophy of the caudate bilaterally.
The patient's diagnosis was confirmed by genetic testing, which showed a CAG trinucleotide repeat on chromosome 4.
Of the following statements, which is most accurate about this patient's disease?
A) Haloperidol can be helpful in symptomatic treatment of the chorea in this disease
B) The choreiform movements will worsen throughout the course of this disease
C) Typical life expectancy after clinical diagnosis with this disease is about 10 years
D) Typical life expectancy after clinical diagnosis with this disease is about 40 years
E) Depression in this disorder typically does not respond to standard antidepressant medications
