When someone with dementia remembers childhood clearly but forgets what happened an hour ago, it’s because the brain holds onto old memories longer. Diseases like Alzheimer’s damage the hippocampus first, making it hard to form new memories, while older ones stored deeper in the brain remain intact. Emotional memories stay strongest, which is why the past often feels more accessible than the present. When this begins affecting daily life—like repeating questions, forgetting recent events, getting lost, or relying more on others—it’s important to seek professional help.

Neurodegenerative diseases gradually damage the brain and nervous system, affecting memory, movement, and behaviour over many years. Conditions like Alzheimer’s, Parkinson’s, Huntington’s, and ALS often involve misfolded proteins, chronic inflammation, low cellular energy, or genetic factors. While there’s no single cure, research is exploring treatments that slow progression, and supportive routines—clear communication, patience, consistency, and gentle movement—can make daily life easier. Seek help if you notice ongoing memory issues, movement changes, confusion, or difficulty with everyday tasks, as early evaluation offers clarity and support.
