Call emergency services for sudden trouble speaking or performing familiar movements, especially with facial drooping, arm weakness, numbness, severe imbalance, vision loss, confusion, or a sudden severe headache.

It is not possible to safely determine at home whether sudden speech difficulty is apraxia, aphasia, or another problem.
New movement or speech problems after a serious head injury, or symptoms accompanied by a seizure or loss of consciousness, also require urgent evaluation.
Routine follow-up may involve a neurologist, rehabilitation physician, primary care clinician, occupational therapist, physical therapist, or speech-language pathologist.
Visits may review progress, safety, communication needs, and whether treatment goals should change.
Arrange a medical review if symptoms are gradually worsening, new daily tasks become difficult, falls increase, or therapy is no longer meeting the person’s needs.
Progressive changes may require further neurological assessment.
Every sign above is quoted from the sofidex article on Apraxia. If you are not sure, err upward — it is always reasonable to be checked.
