Yini ebangela i-Alzheimer's?

Isifo sika-Alzheimer siyisiphazamiso se-neurodegenerative esiqhubekayo esithinta ngokuyinhloko ubuchopho, okubangela ukulahleka kwememori, ukwehla kwengqondo, nezinguquko zokuziphatha.

Imbangela eqondile yesifo sika-Alzheimer ayiqondakali ngokugcwele, kodwa kukholakala ukuthi ibangelwa inhlanganisela yezici zofuzo, ezemvelo nezendlela yokuphila.

Ezinye zezinto ezingase zibe nomthelela ekuthuthukiseni isifo sika-Alzheimer zihlanganisa:

1. Izakhi zofuzo: Kuye kwatholakala izakhi zofuzo ezithile ezandisa ingozi yokuba nesifo i-Alzheimer's, ikakhulukazi izakhi zofuzo ze-apolipoprotein E (APOE).

2. Ubudala: Ingozi yokuthola isifo i-Alzheimer iyanda njengoba umuntu ekhula, futhi abantu abaningi bathola isifo ngemva kweminyaka engu-65.

3. Umlando womkhaya: Ukuba nomlando womkhaya wesifo i-Alzheimer's kungandisa ingozi yokuba nalesi sifo.

4. Ukulimala ekhanda: Umlando wokulimala ekhanda, ikakhulukazi okuholela ekulahlekelweni ukwazi, kungase kwandise ingozi yesifo i-Alzheimer's.

5. Izici zobungozi benhliziyo nemithambo yegazi: Izimo ezinjengomfutho wegazi ophakeme, i-cholesterol ephezulu, nesifo sikashukela zingandisa ingozi yokuthola isifo i-Alzheimer's.

6. Izinto eziphathelene nendlela yokuphila: Indlela yokuphila engahambi kahle, ukudla ngendlela engafanele, nokuntuleka kokugqugquzelwa kwengqondo kungase kwandise ingozi yesifo sika-Alzheimer.

7. Ukuvuvukala: Ukuvuvukala okungapheli ebuchosheni kungase kube nomthelela ekuthuthukiseni isifo i-Alzheimer's.

8. Ukucindezeleka kwe-oxidative: Ukungalingani phakathi kokukhiqizwa kwama-radicals akhululekile nekhono lomzimba lokuwasusa ubuthi kungase kube nomthelela ekuthuthukiseni isifo i-Alzheimer's.

9. Ama-amyloid plaques nama-neurofibrillary tangles: Ukuqongelela kwama-amyloid plaques nama-neurofibrillary tangles ebuchosheni kuyisibonakaliso sesifo sika-Alzheimer, kodwa indima abayidlalayo ekuthuthukiseni lesi sifo ayiqondakali ngokugcwele.

Kubalulekile ukuphawula ukuthi imbangela yesifo sika-Alzheimer iyinkimbinkimbi futhi cishe ihilela inhlanganisela yalezi zici.

Ucwaningo luyaqhubeka ukuze kuqondwe kangcono izindlela eziyisisekelo futhi kuthuthukiswe izindlela zokwelapha eziphumelelayo zalesi simo esibulalayo.

Ukuzikhulula: kwezokwelapha

Le webhusayithi inikezwa ngezinjongo zemfundo nezokwaziswa kuphela futhi ayifaki ukunikeza izeluleko zezokwelapha noma izinsizakalo zobungcweti.

Imininingwane enikeziwe akufanele isetshenziselwe ukuxilonga noma ukwelapha inkinga noma isifo, futhi labo abafuna iseluleko somuntu siqu sezokwelapha kufanele babonane nodokotela onelayisense.

Sicela uqaphele ukuthi inethiwekhi ye-neural ekhiqiza izimpendulo zemibuzo, ayinembile ngokukhethekile uma kuziwa kokuqukethwe kwezinombolo. Ngokwesibonelo, inani labantu abanesifo esithile.

Ngaso sonke isikhathi funa iseluleko sikadokotela wakho noma omunye umhlinzeki wezempilo ofanelekayo mayelana nesimo sezokwelapha. Ungalokothi ungayinaki iseluleko sezokwelapha sobungcweti noma ubambezele ukusifuna ngenxa yento oyifundile kule webhusayithi. Uma ucabanga ukuthi ungase ube nesimo esiphuthumayo sezokwelapha, shayela i-911 noma uye egumbini lezimo eziphuthumayo eliseduze ngokushesha. Ayikho ubudlelwano bokuthi udokotela-isiguli obakhiwe yile webhusayithi noma ukusetshenziswa kwayo. I-BioMedLib noma abasebenzi bayo, noma noma yimuphi umnikeli wale webhusayithi, akenzi noma yimiphi imibono, ecacile noma ecacile, mayelana nolwazi olunikezwe lapha noma ukusetshenziswa kwayo.

Ukuzikhulula: amalungelo obunikazi

I-Digital Millennium Copyright Act ka-1998, i-17 U.S.C. § 512 (i- DMCA) inikeza indlela yokuphendula kubanikazi bamalungelo obunikazi abakholelwa ukuthi okokusebenza okubonakala kwi-Internet kwephula amalungelo abo ngaphansi komthetho we-copyright wase-US.

Uma ukholelwa ngobuqotho ukuthi noma yikuphi okuqukethwe noma okokusebenza okwenziwe kutholakale maqondana newebhusayithi yethu noma izinsizakalo kwephula ilungelo lakho lobunikazi, wena (noma umenzeli wakho) ungasithumela isaziso esicela ukuthi okuqukethwe noma okokusebenza kususwe, noma ukufinyelela kukho kuvinjelwe.

Izaziso kufanele zithunyelwe ngokubhala nge-imeyili (bheka isigaba esithi "Contact" ukuze uthole ikheli le-imeyili).

I-DMCA idinga ukuthi isaziso sakho sokwephulwa kwamalungelo obunikazi kubandakanye imininingwane elandelayo: (1) incazelo yomsebenzi onamalungelo obunikazi oyisihloko sokwephulwa okusolwa; (2) incazelo yokuqukethwe okusolwa ukwephula amalungelo obunikazi nolwazi olwanele ukusivumela ukuthi sithole okuqukethwe; (3) imininingwane yokuxhumana nawe, kufaka phakathi ikheli lakho, inombolo yocingo nekheli le-imeyili; (4) isitatimende sakho sokuthi unokholo oluhle lokuthi okuqukethwe ngendlela ekhonjiwe ngayo akugunyaziwe ngumnikazi wamalungelo obunikazi, noma umenzeli wakhe, noma ngokusebenza kwanoma imuphi umthetho;

(5) isitatimende sakho, esisayinwe ngaphansi kwesijeziso sokufakaza amanga, sokuthi ukwaziswa okusesazisweni kunembile nokuthi unegunya lokuphoqelela amalungelo obunikazi okuthiwa aphuliwe;

futhi (6) isignesha ebonakalayo noma ye-elekthronikhi yomnikazi we-copyright noma umuntu ogunyaziwe ukuba asebenze egameni lomnikazi we-copyright.

Ukwehluleka ukufaka yonke imininingwane engenhla kungaholela ekubambezelweni kokucutshungulwa kwesikhalazo sakho.

What causes alzheimer?

Alzheimer's disease is a progressive neurodegenerative disorder that primarily affects the brain, causing memory loss, cognitive decline, and behavioral changes.

The exact cause of Alzheimer's disease is not fully understood, but it is believed to result from a combination of genetic, environmental, and lifestyle factors.

Some of the factors that may contribute to the development of Alzheimer's disease include:

1. Genetics: Certain genes have been identified that increase the risk of developing Alzheimer's disease, particularly the apolipoprotein E (APOE) gene.

2. Age: The risk of developing Alzheimer's disease increases with age, with most people being diagnosed after the age of 65.

3. Family history: Having a family history of Alzheimer's disease may increase the risk of developing the condition.

4. Head injuries: A history of head injuries, particularly those that result in loss of consciousness, may increase the risk of Alzheimer's disease.

5. Cardiovascular risk factors: Conditions such as high blood pressure, high cholesterol, and diabetes may increase the risk of developing Alzheimer's disease.

6. Lifestyle factors: A sedentary lifestyle, poor diet, and lack of mental stimulation may increase the risk of Alzheimer's disease.

7. Inflammation: Chronic inflammation in the brain may contribute to the development of Alzheimer's disease.

8. Oxidative stress: An imbalance between the production of free radicals and the body's ability to detoxify them may contribute to the development of Alzheimer's disease.

9. Amyloid plaques and neurofibrillary tangles: The accumulation of amyloid plaques and neurofibrillary tangles in the brain is a hallmark of Alzheimer's disease, but the role they play in the development of the condition is not fully understood.

It is important to note that the cause of Alzheimer's disease is complex and likely involves a combination of these factors.

Research is ongoing to better understand the underlying mechanisms and develop effective treatments for this devastating condition.
