Dementia affects ten million individuals globally each year, a number that continues to rise. In the UK, around one million people currently live with dementia, and projections suggest this figure will reach 1.6 million by 2050, as highlighted by the Alzheimer’s Society and various studies.
Alzheimer’s disease, the primary cause of dementia, results in cognitive decline and memory loss due to the brain’s malfunctioning processes, progressively worsening over time. Detecting Alzheimer’s in its early stages can facilitate appropriate medical attention and support for patients and caregivers.
Understanding language modifications can offer insight into early Alzheimer’s symptoms. Speech-related changes, such as pauses, hesitations, and vague expressions, are prominent indicators of cognitive decline. Individuals may struggle to recall specific words, resorting to general terms or circular descriptions to convey their message.
Moreover, using words in improper contexts or substituting them for related terms can signify early Alzheimer’s symptoms. Tasks may be discussed rather than executed, and individuals may exhibit reduced lexical diversity, often relying on common words instead of varied vocabulary. Difficulties in word retrieval or categorization may also surface as the disease progresses.
While aging is a significant Alzheimer’s risk factor, early-onset cases can occur in younger individuals. Consistent and worsening language-related challenges could indicate Alzheimer’s onset, emphasizing the importance of prompt recognition, especially for high-risk groups like individuals with Down Syndrome.
