Physical walking ability is unlikely to be impeded in the absence of neuromuscular problems affecting the lower limbs. Impairment of cognitive function is not likely to be sufficient to cause difficulties satisfactorily using unfamiliar routes independently.

The resulting disability is unlikely to affect their ability to independently carry out activities of daily living. They may be more at risk than a normal person of causing damage or injury in performing everyday activities due to forgetfulness. However this is usually not markedly above a person without early dementia.

The resulting disability may lead them to require assistance with undertaking complex activities.

They may require prompting or supervision to prepare food, take medication, deal with correspondence and financial matters and undertake appropriate activities.

They are not likely to require assistance with most aspects of bodily function and they are not likely to require continual supervision to prevent potentially dangerous behaviours or activities.

Physical walking ability may be significantly restricted as a result of neuromuscular problems affecting the lower limbs. Impairment of cognitive function is likely to cause difficulties satisfactorily using unfamiliar routes independently.

The resulting disability is likely to lead them to require assistance with all activities of daily living. They are likely to require assistance with most aspects of bodily function and they are likely to require supervision to prevent potentially dangerous behaviours or activities.
