From the Guidelines
The most effective new treatments for dementia include FDA-approved monoclonal antibody treatments like lecanemab and donanemab, which have shown modest slowing of cognitive decline by approximately 27-35% in clinical trials, as well as non-pharmacological approaches like transcranial magnetic stimulation and cognitive rehabilitation programs. These treatments work through various mechanisms including reducing brain inflammation, promoting neuronal connections, clearing toxic proteins, and enhancing brain blood flow, though most are most effective when started early in the disease process 1.
Key Treatment Options
- Monoclonal antibody treatments: lecanemab and donanemab, which remove amyloid plaques from the brain
- Non-pharmacological treatments: transcranial magnetic stimulation, cognitive rehabilitation programs, and lifestyle interventions like structured exercise programs and Mediterranean-DASH diet combinations
- Repurposing of existing medications: sodium valproate and lithium, which may help regulate brain inflammation and protect neurons
Disease Management
Dementia management involves a comprehensive approach, including periodic reassessment of cognitive, functional, neuropsychiatric, and behavioral symptoms to monitor disease progression and make adjustments to treatment plans 1. Cholinesterase inhibitors and memantine are commonly used to alleviate symptoms and delay disease progression, although their effects are generally small and clinically marginal 1.
Quality of Life
High-quality, person-centered care, including psychosocial interventions, is now recognized as the first line of prevention and treatment for behavioral and psychological symptoms of dementia, with medication used as a carefully monitored, short-term, last resort in specific cases 1. Lifestyle interventions, such as structured exercise programs and cognitive training, can also help improve quality of life and delay symptom progression.

From the Research
New Treatments for Dementia
- The current mainstays of symptomatic treatment for patients with Alzheimer's disease (AD) are cholinesterase inhibitors, including donepezil, galantamine, and rivastigmine 2, 3, 4, 5.
- These medications have been shown to improve cognitive function, global functioning, and activities of daily living in patients with mild to moderate AD 2, 3, 4, 5.
- Cholinesterase inhibitors have also been found to be beneficial in treating moderate to severe AD, with some studies suggesting that they can delay nursing home placement and reduce caregiver stress 5, 6.
- The use of cholinesterase inhibitors across all stages of AD is recommended, with early initiation and persistent exposure leading to delays in nursing home admission and slower rates of cognitive and functional impairment 6.
- In the moderate to severe stages of AD, therapeutic trials of higher dose cholinesterase inhibitors and the addition of memantine are recommended for patients who are no longer responding to lower doses 6.
Benefits and Risks of Cholinesterase Inhibitors
- Cholinesterase inhibitors have been shown to confer a modest but significant therapeutic benefit in the treatment of AD, despite higher rates of treatment discontinuation and side effects than placebo 3, 5.
- The most common adverse effects of cholinesterase inhibitors include gastrointestinal, cardiorespiratory, extrapyramidal, genitourinary, and musculoskeletal symptoms, as well as sleep disturbances 5.
- Few clinically significant drug-drug interactions with cholinesterase inhibitors have been identified, but patients should be regularly monitored for any potential serious side effects of cholinesterase inhibitor therapy 5, 6.
Comparison of Cholinesterase Inhibitors
- There is no evidence of any differences between donepezil, galantamine, and rivastigmine with respect to efficacy 4.
- Donepezil may have fewer adverse effects compared to rivastigmine, but galantamine and rivastigmine may match donepezil in tolerability if a careful and gradual titration routine is used 4.
