- Informed Consent with patient and family
- Set reasonable expectations
- Medications do not typically alter behaviors (e.g. Agitation in Dementia)

- Minimal clinical benefit, despite Statistically Significant improvement in cognitive function in trials
- Improve neuropsychiatric scores 7 points
- Seven point improvement equals ~1 year of decline
- Benefits may persist for 1-2 years
- Rogers (1998) Arch Intern Med 158:1021-31 [PubMed]
- Meta-analysis shows marginal benefit to risk ratio
- Where NNT is Number Needed to Treat
- NNT for global improvement: 10
- NNT for cognitive improvement: 12
- NNT for significant side effects to stop med: 16
- Lanctot (2003) CMAJ 169:557-64 [PubMed]
- Agents
- Donepezil (Aricept): Preferred agent
- Dose: Start at 5 mg orally at bedtime and increase to 10 mg after 4-6 weeks
- Delays Nursing Home placement by 17-21 months
- Geldmacher (2003) J Am Geriatr Soc 51:937-44 [PubMed]

- Side effects (Nausea, Diarrhea, Bradycardia) may limit use
- Efficacy
- N-Methyl-D-Aspartate (NMDA) Receptor Blocker - Memantine (Namenda, Ebixa in Europe)
- Dose: Start 5 mg orally daily and titrate to 10 mg orally twice daily

Definition (MEDLINEPLUS) |
Dementia is the name for a group of symptoms caused by disorders that affect the brain. It is not a specific disease. People with dementia may not be able to think well enough to do normal activities, such as getting dressed or eating. They may lose their ability to solve problems or control their emotions. Their personalities may change. They may become agitated or see things that are not there. Memory loss is a common symptom of dementia. However, memory loss by itself does not mean you have dementia. People with dementia have serious problems with two or more brain functions, such as memory and language. Although dementia is common in very elderly people, it is not part of normal aging. Many different diseases can cause dementia, including Alzheimer's disease and stroke. Drugs are available to treat some of these diseases. While these drugs cannot cure dementia or repair brain damage, they may improve symptoms or slow down the disease. NIH: National Institute of Neurological Disorders and Stroke |
Definition (MSHCZE) | Chronický, trvalý úbytek duševních funkcí a schopností. Za vznik d. zodpovídají tři skupiny onemocnění mozku. Jde o důsledky aterosklerózy s poruchami prokrvení mozku (skupina ischemicko-vaskulárních d.), důsledky jiných chorobných stavů (symptomatické d., např. v důsledku otrav, alkoholismu, d. při AIDS). Nejč. příčinou d. je Alzheimerova nemoc (s některými vzácnějšími chorobami patří do skupiny atroficko-degenerativních onemocnění mozku). D. postihuje inteligenci, kognitivní funkce, vyšší city. Z kognitivního deficitu jsou patrné zhoršení paměti, afázie, apraxie, agnozie, narušení výkonných funkcí. Mizí schopnost soustředění, otupují se zájmy, člověk se nevyzná v čase, je zmatený, bloudí i v nejbližším okolí (dezorientace). Kortikální d. je způsobena postižením kůry (klasicky u Alzheimerovy nemoci), vyznačuje se normální řečí se značně narušenou sémantikou až afázií, amnézií, poruchami zrakové a prostorové orientace. U subkortikální d. (u Parkinsonovy nebo Huntingtonovy nemoci) bývá výrazněji narušena řeč v důsledku motorických poruch, jazykové schopnosti jsou však postiženy málo. Bývá porucha motivace, snížená aktivita, zpomalení duševních pochodů. V případě d. smíšené (např. vaskulární, multiinfarktová d.) lze pozorovat různé kombinace postižení. Průběh je různý – závisí na příčině a ev. včasné léčbě a různý bývá i u jednotlivých typů. Příznaky se vyvíjejí postupně, u některých forem naučené dovednosti a staré vzpomínky dlouho přetrvávají, mizí však schopnost naučit se novému. Léčba d. je farmakologická a důležité jsou rovněž nefarmakologické postupy z oblasti psychoterapie. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ ) |
Definition (NCI_NCI-GLOSS) | A condition in which a person loses the ability to think, remember, learn, make decisions, and solve problems. Symptoms may also include personality changes and emotional problems. There are many causes of dementia, including Alzheimer disease, brain cancer, and brain injury. Dementia usually gets worse over time. |
Definition (NCI) | Loss of intellectual abilities interfering with an individual's social and occupational functions. Causes include Alzheimer's disease, brain injuries, brain tumors, and vascular disorders. |
Definition (MSH) | An acquired organic mental disorder with loss of intellectual abilities of sufficient severity to interfere with social or occupational functioning. The dysfunction is multifaceted and involves memory, behavior, personality, judgment, attention, spatial relations, language, abstract thought, and other executive functions. The intellectual decline is usually progressive, and initially spares the level of consciousness. |
