Is any of this happening?
Be seen today
Arrange a prompt medical assessment for rapidly worsening memory, behaviour, balance, coordination, speech, or vision.
These symptoms do not necessarily mean CJD, but they need investigation because some possible causes are treatable.
Seek urgent same-day help for:
New difficulty swallowing or repeated choking
Inability to drink enough fluid
Repeated falls or a significant injury
Fever, cough, breathing changes, or possible chest infection
Severe agitation or behaviour that creates an immediate safety risk

Does any of this apply?
Book an appointment
During planned follow-up, report new falls, increasing muscle jerks, medication side effects, changes in eating or drinking, constipation, pain, sleep problems, or growing care needs.
These issues may require changes to support or symptom management.
