=== Social costs === Dementia, and specifically Alzheimer's disease, may be among the most costly diseases for societies worldwide. As populations age, these costs will probably increase and become an important social problem and economic burden. Costs associated with AD include direct and indirect medical costs, which vary between countries depending on social care for a person with AD. Direct costs include doctor visits, hospital care, medical treatments, nursing home care, specialised equipment, and household expenses. Indirect costs include the cost of informal care and the loss in productivity of informal caregivers. In the United States as of 2019, informal (family) care is estimated to constitute nearly three-fourths of caregiving for people with AD at a cost of US$234 billion per year and approximately 18.5 billion hours of care. The cost to society worldwide to care for individuals with AD is projected to increase nearly ten-fold, and reach about US$9.1 trillion by 2050. Costs for those with more severe dementia or behavioral disturbances are higher and are related to the additional caregiving time to provide physical care.
=== Caregiving burden ===
Individuals with Alzheimer's will require assistance in their lifetime, and care will most likely come in the form of a full-time caregiver which is often a role that is taken on by the spouse or a close relative. Caregiving tends to include physical and emotional burdens as well as time and financial strain at times on the person administering the aid. Alzheimer's disease is known for placing a great burden on caregivers which includes social, psychological, physical, or economic aspects. Home care is usually preferred by both those people with Alzheimer's disease as well as their families. This option also delays or eliminates the need for more professional and costly levels of care. Nevertheless, two-thirds of nursing home residents have dementias. Dementia caregivers are subject to high rates of physical and mental disorders. Factors associated with greater psychosocial problems of the primary caregivers include having an affected person at home, the caregiver being a spouse, demanding behaviors of the cared person such as depression, behavioral disturbances, hallucinations, sleep problems or walking disruptions and social isolation. In the United States, the yearly cost of caring for a person with dementia ranges from $28,078–$56,022 per year for formal medical care and $36,667–$92,689 for informal care provided by a relative or friend (assuming market value replacement costs for the care provided by the informal caregiver) and $15,792–$71,813 in lost wages. Cognitive behavioral therapy and the teaching of coping strategies either individually or in group have demonstrated their efficacy in improving caregivers' psychological health.
=== Media ===
Alzheimer's disease has been portrayed in films such as: Iris (2001), based on John Bayley's memoir of his wife Iris Murdoch; The Notebook (2004), based on Nicholas Sparks's 1996 novel of the same name; A Moment to Remember (2004); Thanmathra (2005); Memories of Tomorrow (Ashita no Kioku) (2006), based on Hiroshi Ogiwara's novel of the same name; Away from Her (2006), based on Alice Munro's short story The Bear Came over the Mountain; Still Alice (2014), about a Columbia University professor who has early onset Alzheimer's disease, based on Lisa Genova's 2007 novel of the same name and featuring Julianne Moore in the title role. Documentaries on Alzheimer's disease include Malcolm and Barbara: A Love Story (1999) and Malcolm and Barbara: Love's Farewell (2007), both featuring Malcolm Pointon. Alzheimer's disease has also been portrayed in music by English musician the Caretaker in releases such as Persistent Repetition of Phrases (2008), An Empty Bliss Beyond This World (2011), and Everywhere at the End of Time (2016–2019). Paintings depicting the disorder include the late works by American artist William Utermohlen, who drew self-portraits from 1995 to 2000 as an experiment of showing his disease through art.
== Research == Specific medications that may reduce the risk or progression of Alzheimer's disease include those that impact Aβ plaques, inflammation, APOE, neurotransmitter receptors, neurogenesis, growth factors or hormones. Machine learning algorithms with electronic health records are studied as a way to predict Alzheimer's disease earlier. As of 2025, 182 clinical trials were testing 138 drugs against multiple targets.
