Alzheimer’s Disease Causes: Breaking Myths, Building Understanding

Is Alzheimer’s Simply a Part of Getting Older? 

Noticing certain changes like forgetting names, misplacing keys, and struggling to recall instances or words is common with aging. The occasional relapse can become a matter of concern when such instances come with progressive neurodegeneration. Alzheimer’s disease isn’t an inevitable consequence of aging. The line between normal aging signs and progressive neurodegenerative conditions is blurred. 

So the question arises: What are Alzheimer’s disease causes?

There is no single underlying cause of Alzheimer’s. The condition accounts for complex neural degeneration, genetic susceptibility, vascular health, neural inflammation, and abnormalities in brain proteins. Neural communication in the brain is disrupted, which adversely affects memory, thinking, and the ability to perform everyday tasks.  

Understanding the real Alzheimer’s Disease Causes, associated risk factors, and available treatment plays a pivotal role in improving the patient’s quality of life. The current article breaks common myths and explores the science behind Alzheimer’s and highlights evidence-based treatments.

What Changes Beneath the Surface in the Alzheimer Brain?

Alzheimer’s Slowly Disrupts Memory, Learning Capacity, Thinking and Organizational Skills. The Core Changes in the Brain Include:

• Formation of Amyloid Plaques: The protein fragments clump together outside the brain and disrupt cellular communication
• Tau Tangles: Twisted tau protein fibers form inside the brain, leading to breakdown of the transportation system
• Neuronal Loss: Damaged neurons lose their normal functional ability; slowly they die off, leading to brain shrinkage. Neural inflammation triggers neuronal damage and changes brain connectivity

One Disease, Many Paths: What Can Lead to Alzheimer’s?

Alzheimer’s Disease Causes Include:

• Nerve Cell Death: Amyloid plaque formation or tau protein tangles formation progressively kill neurons. The condition leads to neuronal death in specific brain areas that further spreads to other regions. The commonly affected area is the hippocampus, the brain region that controls memory
• Genetic Factors: Hereditary or genetic cause is high if parents or siblings are affected with the condition. An increase in the APOE ε4 gene significantly increases the chances of getting Alzheimer’s. Aggravation of the genetic cause can increase the disease onset at a younger age
• Traumatic Brain Injury (TBI): Head trauma, neuroinflammation, vascular damage, repetitive concussion increases Alzheimer’s risk
• Lifestyle Factors: Lifestyle factors like smoking, substance use, prolonged exposure to environmental toxins or heavy metals
• Co-Morbid Condition: Presence of certain conditions like metabolic disorder, cardiovascular disease, hypertension, hyperlipidemia, Down syndrome, obesity, etc., increases significant Alzheimer’s risk.

Five Alzheimer’s Myths Worth Rethinking

The Common Myths Around Alzheimer’s Disease Causes Involve:

Myth: Everyone with memory loss with age means an Alzheimer’s patient

Fact: Memory change is part of normal ageing; Alzheimer’s is a progressive cognitive decline that interferes with daily life activities

Myth: If Alzheimer’s runs in my family, I will get it

Fact: Hereditary gene existence increases risk of Alzheimer’s development. It is not inevitable

Myth: Alzheimer’s only affects memory

Fact: Alzheimer’s affects thinking ability, judgement, language, problem-solving, reasoning skills or ability to perform daily life activities

Myth: Nothing can influence Alzheimer’s risk

Fact: Management of co-morbid conditions like lifestyle factors, cardiovascular or metabolic health can manage Alzheimer’s risk at later life stages 

Myth: Keeping the brain active prevents Alzheimer’s

Fact: Cognitive and social engagement supports brain health and resilience; it doesn’t guarantee protection from neural degeneration

What Treatments Are Available for Alzheimer’s Disease? 

The current Alzheimer’s Disease Treatment focuses on symptom management. The diagnostic steps for underlying cause identification include medical history assessment, neurological examination, blood test, MRI, CT scan, and overall health assessment. Based on the diagnosis, clinicians introduce adequate treatment options. Alzheimer’s disease treatment involves:

• Medications: Cholinesterase inhibitors like donepezil, galantamine, or rivastigmine blocks enzymes that speed brain damage. Lecanemab or donanemab boosts the immune system to target amyloid protein buildup in the brain. NMDA antagonist blocks NMDA receptors to prevent brain damage
• Co-Morbid Condition Management: Antidepressants, neuroleptics, antiseizure medication, etc. manage other symptoms
• Physical Activities: Physiotherapists introduce a set of exercises to improve muscle strength, mood swings, sleeping patterns, etc.
• Routine and Environment: Creation and maintenance of structures, labeling household objects, reducing clutter, writing instructions, etc. support the individual in performing daily tasks

*NOTE: The proposed conventional treatment only targets symptom management. However, none address the underlying disease mechanism. 

How is Stem Cell Therapy for Alzheimer’s Evolving? 

The emergence of regenerative medicine has paved a path to address neurological damage. Stem Cell Therapy for Alzheimer’s is a groundbreaking approach that potentially addresses a critical gap in the treatment landscape. Mesenchymal stem cells (MSCs) are widely implicated in preclinical and clinical research for Alzheimer’s patients. Researchers have found MSCs’ ability for cellular regeneration and paracrine signalling. The key benefits reported in early clinical studies include:

• Improved Memory Function: Improvement in cognitive abilities and functional memories
• Neuronal Regeneration: Stimulation of neuronal regeneration, improving brain function
• Quality of Life: Replacement of damaged neuronal cells by healthier ones, improving overall function of the patient. It improves patient’s quality of life [1].

MSCs Introduction Introduces Various Changes at the Cellular Level. This Includes:

• Anti-Inflammation: MSCs release various anti-inflammatory molecules that combat neuroinflammation. Controlling chronic inflammation in the brain creates a supportive microenvironment and slows down disease progression
• Repair Mechanism: MSCs differentiate into distinct cell types based on the stimulation. They replace damaged neurons and activate the repair mechanism in the brain. The mechanism aids in restoration of cognitive function
• Amyloid Buildup Reduction: MSCs reduce amyloid protein accumulation, slow down disease progression and improve cognition
• Immunomodulation: MSCs modulate immune response; they lower the risk of immunogenicity in the recipient patient. This reduces the immune rejection risk and ensures treatment safety

*NOTE: The quality of the stem cells used for Alzheimer’s treatment plays a vital role in the treatment success. Advancells, India is a leading stem cell supplier for various neurological conditions including Alzheimer’s. The cells undergo stringent quality checks and come with a Certificate of Authentication (CoA).   

From Understanding Causes to Shaping the Future of Alzheimer’s Care 

Alzheimer’s treatment isn’t about the one-size-fits-all approach. Identification of the potential cause can support early diagnosis and development of personalized treatment strategies. Currently, clinicians are combining Stem Cell Treatment for Alzheimer’s with conventional approaches to gain improved outcomes. The leap is from managing symptoms to significantly slowing down disease progression and quality life improvement of the patient. The transformation in the treatment landscape supports neuroprotection, anti-inflammation and improvement in cognitive function of the Alzheimer’s patient.

Conclusion 

Alzheimer’s disease is part of the complex age-associated changes, genetic factors, brain pathology and inflammation. The conventional treatment targets the symptomatic changes. A combination of Stem Cell Therapy for Alzheimer’s with a conventional approach improves patients’ overall wellbeing. However, regenerative medicine is still at an early stage of development. In the future, the focus is on the development of large-scale clinical trials to establish long-term safety and efficacy.
