How is Alzheimer diagnosed?

['Faalogologo i lenei itulau']

E faapefea ona iloa le maʻi o le Alzheimer?

E tele auala e mafai ona iloa ai le faamaʻi o le Alzheimer, e aofia ai le faia o se iloiloga māeʻaeʻa a le fomaʻi, o suʻesuʻega e iloa ai le mafaufau ma le neula, o le faia o ni ata o le faiʻai, ma le aveesea o isi māfuaaga e ono māfua ai.

1. Iloiloga faafomaʻi: E faia e se fomaʻi se suʻesuʻega i le tino ma faamaumauina le talaaga o le maʻi ina ia iloa ai po o ā nisi māfuaaga e ono māfua ai ona lē manatua lelei mea po o le faaitiitia o le mafaufau, e pei o faafitauli i le thyroid, le lē lava o vaitamini, po o le maʻi e tupu i le faiʻai.

2. Suʻesuʻega e iloa ai le mafaufau ma le neula: O nei suʻesuʻega e iloiloina ai le manatuaina o mea, le gagana, le foʻiaina o faafitauli, ma isi galuega e iloa ai le mafaufau ina ia iloa ai le telē o le faaletonu o le mafaufau ma iloa ai le eseesega o le lē manatuaina o mea e masani ona tutupu ona o le matua, ma le gasegase o le mafaufau.

3. O le faia o ni ata o le faiʻai: O le faia o ni ata e taʻu o le Magnetic resonance imaging (MRI) po o le computed tomography (CT) e mafai ona iloa ai ni suiga i le faiʻai e ono iloa ai le faamaʻi o le Alzheimer.

E mafai foʻi ona faaaogā le positron emission tomography (PET) e fua ai le tele o nisi o polotini e fesootaʻi atu i le faamaʻi o le Alzheimer.

4. Suʻesuʻega o le toto: Ua faaalia i suʻesuʻega talu ai nei e faapea, o nisi suʻesuʻega o le toto e mafai ona fesoasoani e iloa ai le faamaʻi o le Alzheimer e ala i le fuaina o le maualuga o polotini patino po o faailoga o le ola e fesootaʻi atu i le faamaʻi.

5. Faagasologa o le aveesea: Talu ai e leai se suʻesuʻega e tasi e iloa ai le faamaʻi o le Alzheimer, e masani lava ona aofia ai le aveesea o isi māfuaaga e ono māfua ai āuga e pei o le maʻi o le mafaufau.

E tāua le iloa, e faatoʻā mafai ona iloa le faamaʻi o le Alzheimer pe a uma le oti, e ala i le suʻesuʻeina o le faiʻai.

Peitaʻi, o metotia o loo iai i le taimi nei e mafai ona faamautinoa ai le maʻi o le tagata a o ola pea.

E tāua le vave iloa o le maʻi ina ia amata ai togafitiga ma fuafua ai le lumanaʻi.

How is alzheimer diagnosed?

Alzheimer's disease is diagnosed through a combination of methods, including a thorough medical evaluation, cognitive and neuropsychological tests, brain imaging, and the process of elimination of other possible causes.

1. Medical evaluation: A doctor will perform a physical examination and take a detailed medical history to rule out other possible causes of memory loss or cognitive decline, such as thyroid problems, vitamin deficiencies, or brain tumors.

2. Cognitive and neuropsychological tests: These tests assess memory, language, problem-solving, and other cognitive functions to determine the extent of cognitive impairment and to differentiate between normal age-related memory loss and dementia.

3. Brain imaging: Magnetic resonance imaging (MRI) or computed tomography (CT) scans can help identify structural changes in the brain that may indicate Alzheimer's disease.

Positron emission tomography (PET) scans can also be used to measure the levels of certain proteins associated with Alzheimer's disease.

4. Blood tests: Recent research has shown that certain blood tests can help diagnose Alzheimer's disease by measuring the levels of specific proteins or biomarkers associated with the disease.

5. Process of elimination: Since there is no single definitive test for Alzheimer's disease, diagnosis often involves ruling out other possible causes of dementia-like symptoms.

It is important to note that a definitive diagnosis of Alzheimer's disease can only be made after death through an examination of brain tissue.

However, current diagnostic methods can provide a high level of certainty for a clinical diagnosis while the person is still alive.

Early diagnosis is important for starting treatment and planning for the future.
