While the brain remains one of the greatest frontiers of science, we now know one’s unique biology influences long-term health. This year, we are shining a light on how precision diagnostics—specifically DNA testing—are transforming how we understand and prepare for neurodegenerative conditions like Parkinson’s, Alzheimer’s, and Dementia.
The Power of Your DNAFor many, the mystery of why some people develop neurological conditions while others don't could be found within our genetic code. While lifestyle and environment play massive roles, our genes provide the underlying "blueprint."
Gene by Gene is making advanced genetic testing accessible by looking at specific markers linked to hereditary neurological health:
- Alzheimer’s Disease: Testing for the APOE gene can identify susceptibility to late-onset Alzheimer’s, while panels for PSEN1, PSEN2, and APP can detect the rarer, early-onset familial forms of the disease.
- Parkinson’s Disease: Modern panels can identify variants in genes like LRRK2 and GBA, which are among the most common genetic contributors to Parkinson’s.
- Dementia & FTD: Genetic screening can pinpoint mutations related to Frontotemporal Dementia (FTD) and other rare forms of cognitive decline, providing clarity where symptoms might be overlapping or confusing.
A Future of Precision HealthAs we celebrate Brain Awareness Week, we celebrate the scientists and the technology making "Precision Neurology" a reality. Your brain is unique—and your healthcare should be, too.
