Abstract

Introduction: Alzheimer's disease is the most advanced type of dementia in the globe. Putting an increasing strain on healthcare systems. Almost 6.2 M American (age 65) and older suffering from AD .72 % are 75 year old. One out of every nine adults aged 65 and up suffers from AD (11.3 %)

Phathophysiology: Alzheimer's disease is a cross neurodegenerative illness with a wide range of symptoms. That involve in genetic changes, Education, maturity level, and atmosphere. Now AD is due to some factors like cholinergic hypothesis, beta amyloid and tau protein and neuro mediated inflammation, neurofibrillary tangles of tau.

Symptomatology: mainly over time, more than 90% of all patients experience, restless, anxiety, depression, delusions, dementia, motor abnormality, irritability, sleep problems, hunger disorders, or poor impulse control.

Diagnosis: Furthermore, magnetic resonance spectroscopy is linked to molecular diagnosis (MRS). MicroRNAs (miRNAs), which short non-coding RNAs that motivate gene expression post-transcriptionally. Though Alzheimer's disease (AD) is still a clinical diagnosis, imaging techniques such as PET amyloid and bioparameter in CSF can aid in the evaluation of many patients.

Treatment Avenue: A gene is responsible for the expression of a therapeutic enzyme or a growth factor was used as a primary approach of treatment of AD. However it can treat with medication like AchE inhibitors. Furthermore, Gene therapy and immunotherapy is also use as treatment

Conclusion: AD can be treated with a variety of criteria, including programs, bodily fluids, and imaging studies, in overall studies. AChE inhibitors, and many therapy used for treatment of AD
