While early-onset familial AD is estimated to account for only 1% of total Alzheimer's disease, [3] it has presented a useful model in studying various aspects of the disorder. Currently, the early-onset familial AD gene mutations guide the vast majority of animal model-based therapeutic discovery and development for AD. [45]
In areas where the disease is common, the medication praziquantel may be given once a year to the entire group. [5] This is done to decrease the number of people infected, and consequently, the spread of the disease. [5] Praziquantel is also the treatment recommended by the World Health Organization (WHO) for those who are known to be infected. [5]
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
In epidemiology, case fatality rate (CFR) – or sometimes more accurately case-fatality risk – is the proportion of people who have been diagnosed with a certain disease and end up dying of it. Unlike a disease's mortality rate, the CFR does not take into account the time period between disease onset and death. A CFR is generally expressed ...
However, for some infectious diseases, the symptoms of the clinical disease may appear after the host becomes infectious. In this case, the pre-infectious or latent period has a shorter duration than the incubation period, the infectious period begins before the end of the incubation period and the host can infect others for some time without ...
Co-existing diseases can but don't necessarily contribute to death [56] to various degrees in various ways. In some cases, comorbidities can be major causes with complex underlying mechanisms, and a range of comorbidities can be present once. [57] Pandemics [58] [59] and infectious diseases or epidemics can be major underlying causes of deaths.
The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
