How Do I Take Care of My Aging Parents and Still Survive?

Your hypothalamic-pituitary-adrenal axis was built for sprints, not marathons. Cortisol surges, helps you survive, then retreats. But when the stressor is your mother's deteriorating cognition, that stressor does not have an off switch. It is there at 7am when you call to check she has eaten breakfast. It is there at 3pm when the school calls about your eight-year-old and your mother's GP calls about her blood results at the same time. It is there at 11pm when you lie awake wondering whether she remembered to lock the door. Your HPA axis stays activated. Cortisol stays elevated. And elevated cortisol suppresses immune function, disrupts sleep architecture, increases visceral fat deposition, impairs memory consolidation, and accelerates bone density loss. This is not theory. This is the measurable physiological cost of sustained, unsupported caregiving. Bruce McEwen's allostatic load model at Rockefeller University describes exactly this cascade: the cumulative wear of chronic stress manifesting as elevated inflammatory markers, dysregulated cortisol rhythms, insulin resistance, and cardiovascular strain.

Let me make this personal for a moment. I talked to a woman named Meredith, 48, from Dulwich Hill, who described her HPA axis dysfunction in terms her endocrinologist used: 'Your stress system is stuck in the on position.' She had been taking care of elderly parents for six years, first her father after a stroke, then her mother's dementia. She had not slept through the night in four years. Her morning cortisol was flat. Her afternoon cortisol was paradoxically elevated. She was, in clinical terms, in late-stage allostatic overload. And she told me she felt guilty for going to the doctor at all because the appointment took time away from her mother's care.
