The NHS tells us that Aphasia is when a person “has difficulty with their language or speech. It’s usually caused by damage to the left side of the brain (for example, after a stroke).” However, it can also develop after someone has been diagnosed with dementia. “People with the most common types of dementia, such as Alzheimer’s disease and vascular dementia, usually have a mild form of aphasia.”
Depending on the condition the person is living with, aphasia can come on quickly or more gradually. If the damage to the brain is caused suddenly, such as after a head injury, or a stroke, symptoms of aphasia will usually develop straight away, whereas if the person is living with a progressive condition such as dementia or a brain tumour, they can come on more gradually.
