Until recently, an Alzheimer’s diagnosis was only possible through an autopsy. During the last 10 years, researchers have developed screening tools for diagnosing Alzheimer’s while the patient is alive. Being able to recognize the disease early gives doctors and scientists the ability to develop drugs that target critical characteristics of Alzheimer’s dementia.
What are the treatments for Alzheimer's?
Nowadays, only symptomatic treatments exist for this disease, all trying to counterbalance the neurotransmitter disturbance: 3 cholinesterase inhibitors and memantine. To block the progression of the disease, therapeutic agents are supposed to interfere with the pathogenic steps responsible for the clinical symptoms, classically including the deposition of extracellular amyloid β plaques and intracellular neurofibrillary tangle formation. Other underlying mechanisms are targeted by neuroprotective, anti-inflammatory, growth factor promotive, metabolic efficacious agents and stem cell therapies. Recent therapies have integrated multiple new features such as novel biomarkers, new neuropsychological outcomes, enrollment of earlier populations in the course of the disease, and innovative trial designs. In the near future different specific agents for every patient might be used in a “precision medicine” context, where aberrant biomarkers accompanied with a particular pattern of neuropsychological and neuroimaging findings could determine a specific treatment regimen within a customized therapeutic framework. In this review, we discuss potential disease-modifying therapies that are currently being studied and potential individualized therapeutic frameworks that can be proved beneficial for patients with AD.
What are the treatments for AD?
The acetylocholinesterase inhibitors (AChEIs) which are approved for the treatment of AD are donepezil, galantamine, and rivastigmine.4,5Their development was based in the cholinergic hypothesis which suggests that the progressive loss of limbic and neocortical cholinergic innervation in AD is critically important for memory, learning, attention, and other higher brain functions decline. Furthermore, neurofibrillary degeneration in the basal forebrain is probably the primary cause for the dysfunction and death of cholinergic neurons in this region, giving rise to a widespread presynaptic cholinergic denervation. The AChEIs increase the availability of acetylcholine at synapses and have been proven clinically useful in delaying the cognitive decline in AD.7
What is the FDA approved drug for AD?
The AChEIs donepezil, galantamine, rivastigmine, and the NMDA antagonist memantine are the only FDA-approved AD medications.10
What is the best medication for BPSD?
Antipsychotics and antidepressants remain the main medications for BPSD. Selective serotonin reuptake inhibitors are preferred for treating depression and anxiety. Drugs with low anticholinergic effects and an acceptable tolerability, such as sertraline, citalopram, and escitalopram, are more appropriate. Antipsychotics should be administered only when a significant safety risk for the patient or for the caregivers by aggressive behaviors makes them necessary. Controversial and limited evidence cannot adequately support the use of benzodiazepines, anticonvulsants stimulants, or dextromethorphan/quinidine. Pharmacological approaches to managing BPSD are highly individualized and changeable, depending on patient’s comorbidities, stage of the disease, and symptoms’ severity.21
What is the current research in AD?
At the same time, current research remains focused on the development of therapeutic approaches to slow or stop the disease progression, taking into consideration every new aspect in the biology of the disease, the diagnostic markers, and the precise diagnosis of disease state of every individual and the design of clinical trials. Furthermore, drug development research for AD has become more complicated as preclinical and prodromal AD populations are potentially included in current trials, as well as traditionally included populations of all the clinical stages of AD dementia.38Consequently, current guidance provided by the FDA for AD clinical trials further includes use of fluid or neuroradiological biomarkers in disease staging for preclinical and prodromal AD trials and of a single primary outcome in prodromal AD trials. In addition, the use of clinical trial simulators, Bayesian statistics, and modifiable trial designs is strongly suggested.4

The only conclusive way to diagnose Alzheimer’s is to carry out brain autopsy of the patient’s brain tissue and ascertain whether the subject had Alzheimer’s or any other form of dementia. However, due to the non-feasibility of such methods, to diagnose and conclude the conditions, medical practitioners use tests that examine a patient’s mental ability.
What is the cause of dementia?
Alzheimer's disease (AD), a major cause of dementia, is a progressive neurodegenerative disorder. Dementia includes memory loss and difficulties with thinking, language and problem-solving skills. As per the WHO update, on epidemiology of AD in 2013, the number of people suffering from dementia worldwide is likely to triple by 2050 which was approximately 35.6 million in 2010. The incidence of dementia increases with age, approximately 5-8% are affected over age of 65, the number increases to 25-50% as the age rises over 85. The prevalence of AD for men was lower than that for women by 19-29%. China, USA, India, Japan, Germany, Russia, France and Brazil were the nine countries in descending order of incidence of people suffering from dementia in 2010, and the numbers more than 1 million (USFDA 2013) [1]. There is a protein formed in the brain to form structures called 'plaques' and 'tangles. Microscopically, the neurotic plaques forming amyloid beta peptide (Aβ42) and neurofibrillary tangles (NFTs) composed of hyper phosphorylated tau are the indicators of AD. These proteins are the precursors for the loss of connections between nerve cells, and eventually to the death of nerve cells and loss of brain tissue. We have summarized the pathophysiology, current strategies and future approaches for improvement of the treatment and diagnosis of AD in our review. We aim to give an insight into the current status of diagnosis and future directions to overcome the associated limitations with artificial intelligence. Several proposed theories explain the pathophysiology of neurodegeneration and cause of dementia and are explained in brief in the next section with current advances in understanding.
Is there a drug regimen for Alzheimer's?
Thus, a standard drug regimen ensues in every Alzheimer’s patient, irrespective of the cause, which may not always be beneficial in halting or reversing the disease progression.
Is Alzheimer's disease heterogeneous?
AD is complex and heterogeneous and is inherited according to Mendelian genetics. There are more than 160 mutations reported in three important genes which are responsible for coding amyloid precursor, presenilin 1, and presenilin 2 [67]. ε4 allele of the APOE gene which occurs with a frequency of 14% is the other major risk factor for developing AD; and its frequency increases to ~40% in AD patients and is also related to the onset of earlier age AD dementia and increased Aβ pathology. Amyloid plaques are superabundant in ε4 carriers, with lower Aβ1-42concentration in CSF, with increased Pittsburgh compound B (PiB) shown bound to Aβ aggregates on PET imaging [4]. Familial Alzheimer's disease is inherited from parents and it currently accounts for < 1% of the AD burden [45]. Late-onset AD is genetically and etiologically heterogeneous in nature, with innumerable genes and environmental factors involved in disease progression rate and risk. The strongest and most reliable genetic association involves the epsilon 4 (ε4) allele at the ApoE locus for increased risk of late-onset AD [68, 69]. The ApoE gene encodes for a protein responsible for lipid transport; ε4 allele carriers have increased deposition of amyloid and also show adverse effects on memory and executive function [70]. However, the genotyping of the ApoE locus is complicated as the allelic denomination is determined by a pair of polymorphisms thus a small sample of blood or a cheek swab, can be used for deoxyribonucleic acid (DNA) isolation and thus the determination of ApoE genotype. From now onwards, the association between the ApoE ε4 allele carriers and the occurrence of AD is well-accepted as it also lowers the overall age for onset for AD [66, 67], but does not hold any specific inference for the individual carrier. Therefore, it is to add more accuracy to a complete biomarker panel for AD [71].
What is the best medication for Alzheimer's?
