The selected disease for this paper is Alzheimer’s disease, a progressive neurodegenerative disorder that primarily affects memory and cognitive function. Alzheimer’s disease (AD) is a neurodegenerative condition characterized by the accumulation of amyloid-beta plaques and tau neurofibrillary tangles in the brain, leading to neuronal death and brain atrophy (Alzheimer’s Association, 2022). It is the most common cause of dementia among older adults, representing approximately 60-80% of dementia cases worldwide (Sperling et al., 2014). This paper provides an up-to-date overview of Alzheimer’s disease, focusing on its pathology, signs and symptoms, and available treatments, including experimental approaches.
The pathology of Alzheimer’s disease involves complex biochemical processes. The hallmark features include amyloid-beta plaques, which are extracellular deposits of protein fragments that result from abnormal processing of amyloid precursor protein (APP). These plaques interfere with neural communication and trigger inflammatory responses. The second hallmark, neurofibrillary tangles composed of hyperphosphorylated tau protein, accumulate within neurons and disrupt the microtubule network essential for nutrient and organelle transport (DeTure & Dickson, 2019). As the disease progresses, there is widespread neuronal loss, especially in the hippocampus and cortex, which impairs memory processing and cognitive functions. Recent research highlights the role of genetic factors such as APOE ε4 allele, which increases the risk of developing AD, as well as environmental influences and lifestyle factors like diet and physical activity (Zhou et al., 2021).
The clinical signs and symptoms of Alzheimer’s disease typically develop gradually, beginning with mild memory lapses and progressing to severe cognitive impairment. Early symptoms often include forgetfulness, difficulty learning new information, and confusion about time or place. As the disease advances, individuals may experience language difficulties, disorientation, mood swings, and behavioral changes such as agitation or aggression. In the later stages, patients lose the ability to perform basic daily activities, including eating and personal care, leading to total dependence on caregivers (Alzheimer’s Association, 2022). The symptom progression reflects underlying neurodegeneration, with significant loss of synapses and brain volume observed through neuroimaging studies.
Treatment options for Alzheimer’s disease currently focus on managing symptoms and slowing progression. Approved pharmacological treatments include cholinesterase inhibitors such as donepezil, rivastigmine, and galantamine, which enhance cholinergic transmission by preventing the breakdown of acetylcholine—an essential neurotransmitter involved in learning and memory (Birks, 2015). Another drug, memantine, acts as an NMDA receptor antagonist to reduce excitotoxicity caused by excessive glutamate activity (Reisberg et al., 2003). While these medications provide symptomatic relief, they do not halt disease progression. Experimental treatments aim to target underlying pathology, including anti-amyloid antibodies, tau protein aggregation inhibitors, and neuroprotective agents. Recently, the FDA approved aducanumab, a monoclonal antibody targeting amyloid-beta plaques, representing a significant step toward disease-modifying therapies, although its efficacy remains under debate (Sevigny et al., 2016; US Food and Drug Administration, 2021).
Research continues to explore novel therapeutic strategies, including immunotherapy, gene therapy, and lifestyle interventions. Cognitive training and physical activity have shown promise in delaying cognitive decline, possibly by enhancing neuroplasticity and reducing inflammation. Additionally, advances in biomarker identification, such as cerebrospinal fluid analysis and PET imaging, facilitate early diagnosis and monitoring of disease progression (Jack et al., 2018). Future therapeutic approaches may involve personalized medicine, targeting individual genetic and molecular profiles to optimize treatment efficacy.
In summary, Alzheimer’s disease is a complex neurodegenerative disorder with characteristic pathological features involving amyloid-beta plaques and tau tangles. It manifests through a gradual decline in cognitive and functional abilities, necessitating early diagnosis and intervention. Current treatments offer symptomatic relief, but ongoing research aims to develop disease-modifying therapies. As scientific understanding of AD deepens, integrating pharmacological, biological, and lifestyle strategies holds promise for improving patient outcomes and potentially altering the disease trajectory in the future.
