Aphasia

Aphasia refers to difficulties with language and communication caused by damage to the brain. In the context of dementia, aphasia typically develops gradually as the condition progresses. A person may struggle to find the right words, use incorrect words without realising, have trouble following conversations, or eventually lose the ability to communicate verbally altogether.

In Alzheimer's disease, word-finding difficulties are often one of the earlier language changes. A person might describe an object instead of naming it ("the thing you drink from" instead of "cup") or use a related but incorrect word. As the condition progresses, sentences may become shorter and simpler, and comprehension of complex language may decline.

In frontotemporal dementia, language problems can sometimes be the primary symptom, particularly in the variant called primary progressive aphasia. This can affect either the ability to produce fluent speech or the ability to understand the meaning of words.

For caregivers, supporting a loved one with aphasia requires patience and creativity. Speak slowly and clearly, using simple sentences. Give your loved one time to respond — rushing them often increases frustration. Use gestures, facial expressions, and visual aids to support communication. Ask yes/no questions rather than open-ended ones when your loved one is struggling. Most importantly, focus on connecting emotionally rather than on perfect verbal communication.

Many families find that music, singing, and familiar phrases remain accessible long after conversational language has declined. A speech and language therapist can provide personalised strategies to support communication at each stage of the condition.
