Types of Alzheimer’s Disease: Based on the severity of symptoms of this condition, Alzheimer’s can be categorised into these subgroups:
- Mild Alzheimer’s: This involves the onset of cognitive impairment, which causes difficulty remembering everyday routines such as job responsibilities, bill payment, and others. While these symptoms are not significantly severe, people in this stage can function with some difficulty. They now take a long time to do the identical work they formerly completed more quickly, and this creates a pattern.
- Moderate Alzheimer’s: Due to substantial neuronal damage that occurs in this subtype, the symptoms of this condition intense. The confusion in patients turns more pronounced; with the memory loss, these patients become further dependent on care takers and other family members. Even if the patients are physically well, they cannot perform their daily tasks on their own since their delusional state controls their thoughts and sensory processing.
- Severe Alzheimer’s: In these types of Alzheimer’s disease, the tangles and plaques spread because the death of brain cells, which leads to brain tissue shrinkage. A patient with severe Alzheimer’s has to stay bedridden and can communicate with considerable difficulty.
These subgroups can be considered the stages of Alzheimer’s, which frequently develops in to a severe one from a mild condition. The chances of effective treatment and prevention of its progression are highly dependent on early diagnosis.
What are the 3 types of Alzheimer’s?
- Early-onset Alzheimer’s disease: These types of Alzheimer’s disease affect those younger than 65 years of age. Often, people in their 40s or 50s are diagnosed with the condition. Early-onset Alzheimer’s is uncommon, and those with Down syndrome are at a greater risk. Alzheimer’s disease-related brain alterations, such as the formation of plaques and tangles and the reduction of brain volume, are more prevalent in patients with this condition. The early-onset type also appears to be associated with an abnormality in chromosome 14 of the human genome. Myoclonus, a sort of muscular twitching and spasm, is also more prevalent in early-onset Alzheimer’s.
- Late-onset Alzheimer’s: These types of Alzheimer’s disease are a more prevalent type of the illness, which affects those aged 65 and up. It may or may not be genetic. Researchers have not yet identified a specific gene that causes it. No one knows with certainty why some individuals get it while others do not.
- Familial Alzheimer’s disease (FAD): Doctors are confident that FAD is one of the types of Alzheimer’s disease that is inherited. In afflicted families, at least two generations have been impacted by the illness. FAD accounts for a fraction of all Alzheimer’s disease cases and is prevalent among individuals with Alzheimer’s disease of early onset.
Which stage of Alzheimer’s disease lasts the longest?
Typically, the middle stage of Alzheimer’s disease is the longest and can endure for many years. When Alzheimer’s disease advances, the Alzheimer’s patient will demand a higher degree of care.
What is the most common form of Alzheimer’s?
Alzheimer’s is a prevalent disease. Additional kinds of dementia include dementia with Lewy bodies, which is abnormal protein deposits within nerve cells, vascular dementia, and a cluster of disorders that lead to frontotemporal dementia, which is the degeneration of the frontal lobe of the brain.
Which is the rarest form of Alzheimer’s?
Familial Alzheimer’s disease (FAD) is a different types of Alzheimer’s that is triggered by inherited mutations in genes. Another rare form of dementia is Creutzfeldt-Jakob disease (CJD), which is a deadly form of dementia caused by aberrant, neurotoxic prion proteins.
