Recent Research in Alzheimer’s Disease
Alzheimer’s illness (AD) and vascular dementia (VaD) are normally portrayed as the two most normal reasons for dementia around the world. Dementia is an overall term for loss of memory, language, critical thinking, and other reasoning capacities that are adequately extreme to disrupt day-to-day existence.
Alzheimer’s is the most widely recognized reason for dementia. Messes gathered under the overall term “dementia” are brought about by strange cerebrum changes. These progressions trigger a decrease in reasoning abilities, otherwise called intellectual capacities, adequately serious to impede day-to-day existence and free capacity. They additionally influence conduct, sentiments, and connections. Alzheimer’s sickness represents 60-80% of cases. Vascular dementia, which happens on account of minuscule draining and vein blockage in the cerebrum, is the second most normal reason for dementia. The people who experience the cerebrum changes of various sorts of dementia all the while having blended dementia. Numerous different conditions can cause indications of dementia, including some that are reversible, like thyroid issues and nutrient inadequacies
Conventional and New Treatments
Cholinergic
Cholinergic drugs are the first line of treatments in the treatment of dementia as they help to recover motor abilities and also treat destructive cortical lesions. Its activity is also checked on animal models and beneficial results are reported. Whereas cholinergic stimulation therapy didn’t work on clinical trials so is not established yet. In a recent study, the patients that had dementia were treated with physostigmine which is an anticholinesterase, and then later the enzymes associated with central cholinergic transmission were found to be decreased in brain tissues. Cholinergic rugs can be administered with citicoline precursors or phosphatidylcholine, which increases brain cholinergic transmission and decrease abnormal movements in the body. However, an adverse effect of this treatment is that there is a decrease in prerequisite normal memory and also a decrease in central cholinergic function.
Serotonergic
An example of serotonergic drugs are antidepressants which help to treat post-mortem cortical tissue in AD patients. It is used in the treatments of behavioral and cognitive symptoms of dementia. The clinical observations have given good results in terms of behavioral symptoms.
New Treatments
Antiviral agents
The most critical forms of dementia such as CJD Creutzfelda Jakob disease. It is a progressive form of dementia with very serious outcomes. Resulting in abnormality of muscular tone and movement and encephalopathy caused by a virus, agent in murine scrapie. However, antiviral drugs are without benefits in the animal model, in the absence of any other effective treatment, these are thought justified in the terminal care of CJD patients.
Ethical Social and Legal Concerns
The increasing prevalence of dementia has posed a major worldwide problem for public health. According to current statistics, there will be over 30 million people suffering from this disease. With the majority being the elderly population. Therefore, increasing the burden of financial management and shelter homes. Also, dementia is a very costly disease especially AD with a total estimated cost of US$818 billion globally. This will lead to more sustainable nursing homes and community-based long-term care. The social and ethical concerns are mostly due to public finances and healthcare burdens. Since, the individual capacity to live independently at home, interaction with the social environment and doing jobs, and Daly activities is affected dramatically. In many counties, emotional support to these patients is provided by spouses, children, siblings. This informal caregiving is very hectic and requires physical and mental devotion to the patient. Care provision frequently involves high socioeconomic and psychophysical costs for caregivers. This can result in caregivers’ negative psychological consequences in the form of emotional and psychological stresses, mood disturbances such as anxiety and depression, and other psychological conditions. However, this leads to the financial, social, and legal burden on the public.
