Dementia

What is Dementia?

Dementia, also called major neurocognitive disorder, is a significant and lasting decline in thinking skills, such as memory, language, attention or planning, that also reduces a person's ability to manage everyday tasks.^[1] It is not a single disease and it is not a normal part of aging. No cure exists for any of its causes.^[1]

Common symptoms

Early symptoms depend on the cause. In typical Alzheimer disease, the first and most common symptom is short-term memory loss, followed by trouble with problem-solving, judgment, language and spatial skills.^[2] People often lose the ability to manage money, medicines or cooking early on, and many do not recognize their own difficulties.^{[1, 2]}

Behavioral and psychological symptoms are also common. These include apathy, anxiety, depression, delusions, agitation, and disturbed sleep and appetite.^[3] Later stages bring problems with movement, incontinence and growing dependence on caregivers.^[2]

Causes and risk factors

Dementia has many possible causes, including Alzheimer disease, vascular dementia, frontotemporal dementia, Lewy body dementia and Parkinson disease.^[3] Alzheimer disease accounts for at least two thirds of cases in people 65 and older.^[2]

Age is the strongest risk factor. Cardiovascular risk factors such as high blood pressure and diabetes, smoking, family history and head injury also matter.^[1] In a pooled analysis of 76 cohort studies, insomnia, short or long sleep duration and poor sleep quality were each linked with a higher risk of cognitive decline or dementia, although these studies cannot show that poor sleep is the cause.^[4]

How it is diagnosed and treated conventionally

Diagnosis is made by a physician from the history, cognitive testing, a neurological exam, blood tests and brain imaging, to identify the cause and rule out treatable problems. Newer biomarker tests are also used in Alzheimer disease.^[2]

There is no cure, but treatment can help with symptoms. Cholinesterase inhibitors may reduce some cognitive and behavioral symptoms, and newer medicines aim to moderate Alzheimer progression in selected patients.^{[2, 5]} In a network meta-analysis of trials, exercise was linked to lower overall behavioral symptom scores, massage and music to lower depression scores, and massage combined with aromatherapy or music to lower agitation scores.^[6]

Why Dementia calls for a whole-person approach

Dementia affects the whole person and the whole household. Other medical conditions, sleep, mood, behavior and caregiver strain all shape daily life, and some can be addressed even when the underlying disease cannot.^[3]

Supportive care in dementia therefore aims at comfort and daily function. It does not aim to change the course of the disease.

Sleep

Sleep disturbance is a common symptom in dementia and is classed among the behavioral and psychological symptoms of dementia.^[3] Poor sleep is also associated with higher risk of cognitive decline in long-term studies.^[4]

Mood, agitation and behavior

Depression, anxiety, apathy and agitation are frequent, and these symptoms can significantly affect the course and management of dementia.^[3] Non-drug approaches are generally tried before additional medicines.

Vascular health

Vascular dementia results from reduced blood flow to the brain, and vascular risk factors also contribute to other types.^{[1, 3]} Managing blood pressure, diabetes and other vascular risks is a medical task, and complementary care should not be a substitute for it.

Physical activity and movement

Exercise combined with usual care ranked best among non-drug treatments for overall behavioral symptoms in a network meta-analysis of 43 trials, with moderate-certainty evidence.^[6]

Acupuncture as supportive care in Dementia

What the research shows

Evidence that acupuncture helps people with dementia is limited. In a 2026 trial of 160 people with mild Alzheimer disease who were taking donepezil, real acupuncture three times a week for 14 weeks improved cognition scores more than sham acupuncture. The benefit was gone 14 weeks after acupuncture stopped, and the authors described acupuncture as a symptomatic add-on, not a disease-modifying treatment.^[7]

For vascular dementia, a meta-analysis of 34 trials with 2,672 patients found improved cognitive test scores with acupuncture, but no clear change in daily activities. The authors concluded that evidence was low to moderate in quality and that acupuncture should be used cautiously.^[8] A Cochrane review found no suitable placebo-controlled trials and called the effect uncertain.^[9] A review of 48 trials in vascular cognitive impairment, which is a milder and broader condition, found benefit but rated the certainty as low or very low.^[10]

For sleep problems in dementia, a meta-analysis of 10 trials with 721 people found better sleep scores with acupuncture, especially alongside usual medicines. The authors rated the certainty low to moderate and noted the low quality of the included trials.^[11]

How acupuncture may work

Acupuncture may reduce oxidative stress in the brain, according to a review of 22 animal studies in vascular dementia. The review found that most of the studies had methodological flaws, and animal results do not show the same effect in people.^[12] This is a proposed mechanism, not a settled one.

What treatment involves

Treatment uses fine, sterile, single-use needles placed at points on the head, body and limbs, usually left in place for about 20 to 40 minutes, with a course of several visits and regular reassessment. The Alzheimer trial above used three sessions a week.^[7] Treatment should be adapted to comfort and the person's ability to rest calmly.

In prospective studies, about 9 in 100 patients had a minor reaction such as brief bleeding, soreness or bruising, and serious events occurred in about 1 in 10,000.^[13] Tell the practitioner first if the person has a bleeding disorder, takes blood thinners, or has a pacemaker (relevant to electroacupuncture). If a person with dementia cannot reliably report discomfort, a caregiver should help watch for it.

Ayurvedic medicine as supportive care in Dementia

The Ayurvedic view

In classical Ayurveda, dementia corresponds to a loss of mind and intellect called Cittanasa, and age-related decline was treated within a branch called Rasayana, or rejuvenation therapy.^[14] In this traditional framework, it is linked to aging and imbalance of the doshas, especially Vata. These are traditional categories, not biomedical diagnoses.

Therapies that may be used

Supportive care is individualized and traditionally includes:

• Regular, simple meals and a steady daily routine, which also helps with sleep
• Gentle warm oil massage and calming practices
• Herbs such as brahmi (Bacopa monnieri), traditionally used for memory and mental function

Panchakarma procedures are generally not appropriate in dementia, because the person is usually older, may be frail, and may not be able to consent to or tolerate the procedures. They should not be used during acute illness. We would only consider gentle therapies, with the treating physician's knowledge.

What the research shows

The research on Ayurveda for dementia is very limited. We found no controlled clinical trials of Ayurvedic treatment in people with dementia. The best-studied herb is Bacopa, and a meta-analysis of 9 placebo-controlled trials with 518 people found improved speed of attention on some tests. The authors said that a large head-to-head trial is still needed to show efficacy in healthy people or people with dementia.^[15]

A small two-month trial of 62 people with mild cognitive impairment reported mixed results for Bacopa against placebo: no difference in the overall cognitive score at some time points, differences in attention and verbal fluency, an overall improvement by the end of the study, and no effect on sleep quality.^[16] Mild cognitive impairment is an earlier stage than dementia, and these results should not be applied to people with dementia.

Herbal medicine as supportive care in Dementia

Herbs and formulas that have been studied

The most studied herb is Ginkgo biloba. Chinese herbal formulas have been studied in Alzheimer disease and in vascular dementia, for example formulas such as Naoxintong and Shenfu decoction in vascular dementia.^{[17, 18]}

What the research shows

Overall evidence is limited and of low quality. A 2026 Cochrane review of 82 trials found that in people with dementia, ginkgo may bring small to moderate benefits at six months, but the certainty was low and the results varied between studies. In mild cognitive impairment, ginkgo probably has little or no effect, and in people with only subjective memory complaints it may carry a higher risk of side effects at three months.^[5]

A 2025 meta-analysis of 13 studies of traditional Chinese medicine in Alzheimer disease found better cognitive scores than controls but no significant difference in neuropsychiatric symptoms or daily living, and called for larger, more rigorous trials.^[18] An overview of 10 systematic reviews in vascular dementia found that herbal medicines might improve cognition, but evidence was limited by few randomized trials and incomplete safety reporting.^[17]

Safety and herb-drug interactions

Herbs can interact with medicines, and people with dementia often take several. Ginkgo has been reported to cause bleeding when combined with warfarin or aspirin, to raise blood pressure with a thiazide diuretic, and to cause coma with the antidepressant trazodone. Other herbs, including danshen, interact with warfarin.^[19]

Any herb must be reviewed against the full medicine list, including cholinesterase inhibitors, memantine, antidepressants, anticoagulants and sedatives, with the prescriber's knowledge. About one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[20] A caregiver should store, supervise and give any products, and tell us about liver or kidney disease.

Translating traditional medicine into modern biological language

The links here are interpretation, not equivalence. Chinese medicine often describes memory decline in terms of weak kidney essence, or of blood stasis and phlegm affecting the mind. Researchers studying acupuncture look at oxidative stress in the brain in animal models of vascular dementia, which loosely parallels those ideas.^[12]

In Ayurveda, Rasayana is the traditional branch of care for aging and age-related disorders.^[14] No study shows that a dosha or Rasayana corresponds to a specific brain process or slows neurodegeneration.

How this care fits with your medical care

Dementia needs diagnosis and ongoing management by a physician or specialist. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care. We do not diagnose dementia, prescribe or change medicines, or replace your neurologist, primary care physician or other clinicians.

Please bring the diagnosis and test results, a full list of medicines and supplements, and the name of the person who helps manage care. Do not stop or change prescribed medicines without your prescriber.

When to seek urgent medical care

Sudden changes in a person with dementia can signal a treatable emergency, and should not be assumed to be disease progression.

• Sudden worsening of confusion or alertness over hours or days, which can signal delirium from infection or medicine
• Face drooping, arm weakness, trouble speaking or sudden vision loss, which can mean a stroke
• A fall or head injury, especially in someone on blood thinners
• Refusing food or fluids, or signs of dehydration
• Aggression, hallucinations or behavior that puts the person or others at risk
• A person with dementia who is lost or has wandered away

If any of these occur, call 911 or go to the nearest emergency department.
