Avoiding Dementia


Dementia Prevention in Ovarian Cancer Care

Study Reference: Clinical Guideline / Review | JAMA (2026) | DOI: 10.1001/jama.2026.2853908

Ovarian cancer is predominantly a disease of older women, a demographic facing a significant parallel health burden: for women aged 55 and over, the lifetime risk of developing dementia is 42%. With over 500,000 individuals currently living with dementia in Australia and no cure available, preventative health measures are paramount. Emerging evidence indicates that up to 45% of dementia cases could be prevented or delayed by addressing modifiable risk factors. For support nurses guiding women through ovarian cancer treatment and survivorship, integrating discussions on cardiovascular health, sensory management, and social engagement offers a vital opportunity to protect long-term cognitive health.

Key Points

  • High Lifetime Risk in Older Women: Women aged 55 or older face a 42% lifetime risk of dementia, with overall incidence rising alongside advancing life expectancy.

  • Vascular and Metabolic Targets: Key clinical intervention points include rigorous management of hypertension, lipid reduction via statins, and optimal blood glucose control.

  • Sensory and Social Factors: Mid-to-late-life hearing loss and social isolation represent major, often overlooked, drivers of cognitive decline.

  • Relevance to Oncology Care: Cancer treatments (such as chemotherapy-induced neurotoxicity or surgical menopause) can exacerbate cognitive vulnerability, making concurrent vascular and lifestyle risk reduction particularly impactful.

What This Means for Ovarian Cancer Support Nurses

Clinical ChallengePractical Action 
Cognitive Health & Holistic AdvocacyReframe survivorship care to include brain health; encourage callers to discuss routine vascular checks (blood pressure, lipids, blood sugar) with their primary care physician alongside oncology follow-ups.
Vascular Risk & Metabolic ManagementHighlight the dual benefit of cardiovascular control; reassure patients that managing hypertension and diabetes protects both surgical/oncologic outcomes and long-term cognitive function.
Sensory Loss & Social ConnectionPrompt callers regarding hearing checks and social support; advise that treating hearing loss and maintaining community connections are proven strategies to buffer against cognitive decline.
Addressing Fear & Promoting AgencyValidate anxieties regarding cognitive changes or "chemo brain"; empower callers with actionable, evidence-based lifestyle modifications rather than leaving them with a sense of inevitability.

An impossible dream?

Reducing ovarian cancer mortality through screening: an impossible dream? https://tinyurl.com/4524jh8f The history of screening tests for ovarian cancer is not good. Two huge trials; the UKCTOCS with  more than 200,000 recruits over 20 years and the PLCO trial with more than 3 million pathology samples  sho wed no benefit in terms of survival from ovarian cancer. This article addresses the stages of ovarian cancer using  an alternative approach called the clinical continuum,  which divides cancer into 3 phases ,  no disease, pre-clinical  (detectable disease) , and  clinical (overt cancer). Obviously for a screening test to be effective ,   cancer needs to be detected before the clinical  phase. However, ovarian cancer is unlike other cancer in that the precursor occurs in the fallopian tube and the re is an argument to say that ,  by the time ovarian cancer has occurred ,  it is always advanced and metastatic .   T his time in...

Sugar doesn’t feed cancer

Revisiting the Warburg-Based “Sugar Feeds Cancer” Hypothesis: A Critical Appraisal of Epidemiological, Experimental and Mechanistic Evidence https://tinyurl.com/3v2tysdt Many clinical care professionals receive queries from cancer patients about whether they should modify their diet to red u ce consumed sugar. This concern is based on a misunde r standing of some basic medical research known as the Warbur g effect. Research from 1956 show ed that cancer cells alter their metaboli sm to enable increased glucose uptake and increase energy production. A misunderstanding of this effect has led to incorrect dietary advice to cancer patients suggesting sugar restriction may be benefi cial. As a result, malnutrition , which is already a s i gnificant cause of morbidity for cancer patients , can be exacerbated . No hard evidence that low sugar diets alter survival exists. Some anecdotal reports suggest a slight correlation with risk. This study is a n appraisal of all credible re...

Recurrent OC subtypes

Myeloid cell networks govern re-establishment of original immune landscapes in recurrent ovarian cancer https://tinyurl.com/47mcxyde Women unfortunate enough to develop a recurrence of ovarian cancer show a range of responses to repeat chemo. This study looks at the immune response to the cancer and the survival outcomes. About half of these women show the presence of tumour infiltrating lymphocytes, (TIL),  suggesting an active cell-mediated immune response. This is associated with better survival. Most of those women also display defective DNA repair with Homologous Recombination Deficiency (HRD). The immune response is stimulated by increased antigen s such as PD-1 , which suggest that immunotherapy with immune checkpoint inhibitors could be of benefit. However, in practice this has not seen to be true. T o understand why this is the case the authors reviewed the immune status of abut 600 patients with ovarian cancer using digital pathology. They subdivided the immune r...
