Is any of this happening now?
Call 911
Call emergency services for an immediate suicide plan or attempt, severe choking, inability to breathe, loss of consciousness, or a serious injury.
Sudden weakness, facial drooping, or speech loss also needs emergency care because these can be signs of a stroke, not the usual gradual progression of Huntington disease.
Other emergency signs, for anyone
Someone who is struggling to breathe, gasping, choking, or cannot get words out
Someone who has chest pain, tightness or pressure lasting more than a few minutes
Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
Someone who is unconscious, or cannot be woken
Someone who is bleeding heavily and it will not stop with firm pressure
Someone who has had a seizure that will not stop, or does not wake up afterwards
Someone who has lips or skin that look pale, blue, grey or blotchy
Someone who you believe has taken an overdose or swallowed something poisonous

Is any of this happening?
Be seen today
If you already have the condition, request a prompt review for worsening swallowing, repeated coughing during meals, unexplained weight loss, frequent falls, major behaviour changes, or possible medicine side effects.
Seek urgent medical help if someone:
Has new or worsening thoughts of suicide or self-harm
Is unable to eat or drink safely
Develops fever, breathing trouble, or marked drowsiness after choking
Becomes severely agitated, confused, or unable to stay safe

Does any of this apply?
Book an appointment
Arrange a routine medical review if you or someone close to you has gradually developing involuntary movements, changes in coordination, or persistent changes in thinking, mood, or behaviour.
This is particularly important when Huntington disease is known in the family.
Every sign above is quoted from the sofidex article on Huntington disease. If you are not sure, err upward — it is always reasonable to be checked.
