Facing a Genetic Diagnosis: One Woman's Journey with Early Onset Dementia

The question of whether you take care of your future by seeking a genetic diagnosis is a profound dilemma. Laura Sides faced this exact choice after watching her father, a dedicated GP, struggle with a rare form of early onset Alzheimer's. Growing up, she shared a close bond with him, eventually leaving university to provide care as his condition progressed. During a hospital visit, she learned she had a 50/50 chance of inheriting the same illness, a prospect she initially suppressed while navigating the loss of both parents.

After moving to Melbourne, Australia, the possibility of inheriting the condition began to weigh heavily on her. In 2013, she consulted a specialist who explained that a test could confirm with near-certainty if she carried the gene. The results, she was told, would indicate an expected age of decline between 46 and 48. Though she initially declined, her perspective shifted as she entered her 30s. Following six months of genetic counseling, she underwent the testing process.

The Life-Changing Result

The day she received her results, she attended the appointment alone. The confirmation that she had inherited the gene for the "London variant" of dementia was a moment of profound shock. While she struggled to process the news, the diagnosis prompted a reassessment of her priorities. She eventually felt a strong pull to return to the United Kingdom to be closer to her family, particularly as her sister prepared to welcome a child.

Receiving a genetic diagnosis for early onset dementia forces a complete reevaluation of one's future and priorities.

Despite the diagnosis, Sides has found purpose in participating in medical trials, viewing her involvement as a positive contribution despite the difficult circumstances. Now 43, she remains focused on the present. While she acknowledges that she will eventually face a decline, she notes that the prospect does not prevent her from living her life or sleeping soundly at night.
