That’s why, often, caregiving duties also fall on the children of these families, as demonstrated by Anne in the story above. Individuals with early-onset Alzheimer’s and their caregivers face a unique set of challenges. [providencefremont.com]

If they were positive, would she have to worry their care might eventually fall to her? Their parents don't want to know if their children test positive. Tyler's dad once told him if they had known what would happen, they may not have had children. [azcentral.com]

Age of onset before 60 years suggests an EOAD and needs a pedigree. [orpha.net]
Furthermore, our results suggest that the burden of these risk variants is associated with familial clustering and earlier-onset of AD. Although these variants are not associated with risk in the eADAD, they may be modulating age at onset. [biorxiv.org]

As a result, eFAD is often accompanied by psychiatric complications such as depression and agitation. While eFAD and LOAD are outwardly the same, the underlying process that leads to eFAD is distinct from that which results in LOAD. [alzforum.org]

Other Pathologies
- Neurofibrillary Tangle
Defining EOAD Alzheimer's disease (AD) is characterized by adult onset progressive dementia that is associated with beta-amyloid plague formation, cerebral cortical atrophy, and intraneuronal neurofibrillary tangles. [disabled-world.com]
These mutations result in an incompletely understood cascade of events resulting in neuronal death, synapse loss, and the formation of neurofibrillary tangles and senile plaques. [orpha.net]
ADには、老人斑と neurofibrillary tangles (NFTs) が見られる。アミロイドベータ(Abeta)は、老人斑の主要な構成成分であるが、これは細胞とオルガネラの機能に様々な病的効果を引き起こす。細胞外の Abeta オリゴマーは、細胞表面の death receptor の活性化を通じ、カスパーゼを活性化する。 [genome.jp]
It is believed the genes may not cause the problem itself, but simply increase the likelihood of formation of plaques and tangles or other related pathologies in the brain. [mercyhealth.com]
Treatment
The material is in no way intended to replace professional medical care by a qualified specialist and should not be used as a basis for diagnosis or treatment. [orpha.net]
Treatment of EOAD Treatment of Alzheimer's disease is largely supportive. Treatment for aggression, depression, seizure activity, sleep disturbances as well as any hallucinations the person may experience are all managed on an individual basis. [disabled-world.com]
Treatment The progression of Alzheimer’s disease symptoms can be slowed but not stopped. [mercyhealth.com]
Prognosis - Alzheimer disease type 4 course of disease can continue for up to 25 years Treatment - Alzheimer disease type 4 There is no cure for AD. Treatment is supportive and based on the signs and symptoms present in each person. [checkorphan.org]
Prognosis
Diagnosis of this entity is important to provide correct prognosis and adequate care to patient and to recognize at risk family members by genetic testing after proper counseling. [annalsofneurosciences.org]
Prognosis The disease is progressive; patients have deterioration in their behavior, cognition, and ability to perform activities of daily living. At an advanced stage, patients are confined to bed. [orpha.net]

Etiology
Etiology EOAD is the consequence of either PSEN1 mutations (69%), APP mutations (13%), or APP duplication (7,5%), and exceptionally of PSEN2 mutations (2%). [orpha.net]
There may be a further genetic factor involved in the etiology of autosomal dominant early onset AD. Received February 26, 2002. Accepted September 26, 2002. [neurology.org]
A diagnosis of possible AD dementia is made when the patient meets most of the AD criteria, but has an atypical course or an etiologically mixed presentation. 6 This may consist of an atypical onset (eg, sudden onset) or atypical progression. [bcidaho.com]
Epidemiology
Summary Epidemiology EOAD represents less than 1% of all cases of AD. Clinical description Initial findings of EOAD are mainly disorders of episodic memory or changes in behavior. [orpha.net]
