The term "early onset Alzheimer's disease" refers specifically to Alzheimer's that occurs in individuals typically under the age of 65. It does not mean the disease is just starting; rather, it indicates that the symptoms and diagnosis happen at a younger age compared to the more common late-onset Alzheimer's, which typically affects older adults. Early onset Alzheimer's can progress similarly to late-onset, but it may have different genetic and environmental factors influencing its development.
Alzheimer's disease is not a sex-linked condition; it is primarily influenced by genetic and environmental factors. While certain genetic mutations associated with early-onset Alzheimer's are located on chromosomes, they are not linked to sex chromosomes (X or Y). The most common form, late-onset Alzheimer's, involves multiple genes and is affected by age and lifestyle rather than being directly tied to sex-linked inheritance. Thus, Alzheimer's affects individuals regardless of their sex.
Alzheimer's disease is primarily associated with complex genetic factors rather than being classified as a simple recessive or dominant trait. Certain genetic mutations, such as those in the APP, PSEN1, and PSEN2 genes, can lead to familial Alzheimer's disease, which is typically inherited in an autosomal dominant manner. Additionally, the presence of the APOE ε4 allele is a significant risk factor for late-onset Alzheimer's, but this does not follow a straightforward Mendelian inheritance pattern. Overall, Alzheimer's involves multifactorial genetics, including both genetic and environmental influences.
Metals have been implicated in neurodegenerative diseases, although it is unlikely that they are the sole cause for any of them. Interest in a possible connection between aluminum and Alzheimer's disease arose when autopsies of the brains of Alzheimer's patients revealed higher than normal concentrations of aluminum. The toxicity of aluminum has been the subject of much controversy in the past few decades. Although it is generally believed that the metal is harmless to human health, a role for aluminum in Alzheimer's disease has been suggested. The exact mechanism of aluminum toxicity is not known and a direct causal role has not been determined. Many scientists believe that the buildup of aluminum in the brain of Alzheimer's patients is the result of damage to nerve cells, rather than the cause of this damage. Some studies have even suggested that the processing of the brain tissue at autopsy may artificially raise aluminum levels. However, there is some evidence showing that aluminum compounds may increase the formation of agents called reactive oxygen species. These substances, which are constantly formed in the human body, have been shown to damage proteins and play a role in various diseases. In relation to Alzheimer's disease, these compounds may play an important role in nerve cell damage. Aluminum is also known to alter the activity of several key enzymes in the central nervous system. Further, there are also some studies showing elevated risk of Alzheimer's disease in areas where there is high concentration of aluminum in drinking water. This is in contrast to many studies examining antacid exposure and Alzheimer's disease that have been largely negative (antacids contain thousands of times more aluminum than the amounts taken in through drinking water). Exposure to aluminum from cooking utensils, baking powder, deodorants, or antacids is not sufficient to cause the disease. In total, these studies provide some evidence that potential links between aluminum and Alzheimer's disease exist, but this area requires continued research efforts.

He suffers from a from of Alzheimer's called "posterior cortical atrophy". It is a rare form, and unlike usual Alzheimer's, it does not deteriorate memory and such but rather affects the vision. IE. The patient can speak and remember fine, but has difficulty writing or reading.
Hemophilia is not a disease, my dear friend. Rather, it is a genetic disorder regarding the blood.
Edema is a sign of an underlying problem, rather than a disease unto itself
Swollen lymph nodes would be a symptom of a disease rather than the disease itself.
It appears in route 113 and it is rather rare.
No....its not a genetic disease but rather an infectious disease cause bu bacteria or virus.
In Wilson disease, copper does not pass from the liver into the bile, but rather begins to accumulate within the liver.
