Understanding Neurodegenerative Diseases
Neurodegenerative diseases are a group of disorders that primarily affect the neurons in the brain. These diseases progressively degenerate and adversely impact an individual’s cognitive functions, motor skills, and overall quality of life. The exact causes of neurodegenerative diseases are often complex and multifactorial, involving both genetic and environmental factors.
Definition of Neurodegenerative Diseases
Neurodegenerative diseases refer to a broad class of conditions characterized by the gradual loss of structure or function of neurons, leading to the impairment of neurological functions. Common examples include Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and Amyotrophic Lateral Sclerosis (ALS). These diseases typically result in the progressive loss of memory, movement, coordination, and other essential functions, leading to significant disability and a reduced lifespan.
Common Neurodegenerative Diseases
Among the various neurodegenerative diseases, a few are particularly prevalent in Malaysia:
-
Alzheimer’s Disease: This is the most common form of dementia, characterized by a progressive decline in cognitive functions, memory loss, and behavioral changes.
-
Parkinson’s Disease: A degenerative disorder that affects movement, Parkinson’s disease leads to shaking, stiffness, and difficulty with balance and coordination.
-
Huntington’s Disease: An inherited condition that causes the progressive breakdown of nerve cells in the brain, resulting in uncontrolled movements, cognitive decline, and psychiatric symptoms.
-
Amyotrophic Lateral Sclerosis (ALS): Also known as Lou Gehrig’s disease, ALS is a motor neuron disease that causes the degeneration of motor neurons, leading to muscle weakness, paralysis, and eventually respiratory failure.
Prevalence of Neurodegenerative Diseases in Malaysia
Neurodegenerative diseases pose a significant health burden in Malaysia, primarily due to the aging population. According to statistics, the prevalence of neurodegenerative diseases is increasing, and they are projected to become a major public health concern in the coming years.
Alzheimer’s disease, in particular, has seen a notable rise in prevalence, with an estimated 150,000 Malaysians currently living with the condition. Parkinson’s disease and other neurodegenerative disorders also contribute to the overall burden of neurological diseases in the country. The increasing prevalence of these conditions highlights the urgent need for effective treatment strategies and interventions.
What are Stem Cells?
Stem cells are unique cells that possess the remarkable ability to develop into various specialized cell types in the body. They serve as a foundation for the body’s growth, repair, and regeneration processes throughout life. Unlike other cells in the body, stem cells are capable of self-renewal and can divide extensively to form new cells.
Definition of Stem Cells
Stem cells are undifferentiated cells that have the potential to differentiate into specialized cell types and regenerate damaged tissues or organs. They are characterized by their ability to renew themselves through cell division and differentiate into various cell lineages, including neurons, muscle cells, blood cells, and more.
Types of Stem Cells
There are different types of stem cells, each with varying differentiation potential and origin:
-
Embryonic Stem Cells (ESCs): Derived from embryos during the blastocyst stage, these pluripotent stem cells have the potential to differentiate into all cell types in the body. Their use in research and therapeutics is highly regulated due to ethical considerations.
-
Adult Stem Cells: Also known as somatic or tissue-specific stem cells, these stem cells are present in adult tissues and play a vital role in tissue maintenance and repair. They are relatively restricted in their differentiation potential compared to embryonic stem cells.
-
Induced Pluripotent Stem Cells (iPSCs): These stem cells are artificially derived from adult cells, such as skin cells, through reprogramming techniques. iPSCs have characteristics similar to embryonic stem cells, providing a valuable alternative for potential therapeutic applications.
Properties and Characteristics of Stem Cells
Stem cells possess several key properties that distinguish them from other cells:
-
Self-Renewal: Stem cells have the ability to divide and produce identical copies of themselves, allowing them to replenish their population.
-
Differentiation Potential: Stem cells can differentiate into specialized cell types, giving rise to various tissues and organs.
-
Plasticity: Some stem cells exhibit plasticity, enabling them to differentiate into cell types beyond their tissue of origin. This property has significant implications for regenerative medicine.
-
Immortality: Stem cells can undergo numerous divisions without losing their functionality, ensuring a long-term source of cells for therapeutic purposes.
Understanding these properties and characteristics of stem cells is crucial for exploring their potential in treating neurodegenerative diseases.

Review of Stem Cell Therapy
Stem cell therapy involves the use of stem cells to replace or repair damaged cells and tissues in the body. In the context of neurodegenerative diseases, researchers and clinicians have been exploring the use of stem cells to regenerate neurons and restore neural function.
Mechanism of Action in Neurodegenerative Diseases
The potential mechanisms through which stem cell therapy may benefit individuals with neurodegenerative diseases include:
-
Neural Differentiation: Stem cells can differentiate into neural cells, including neurons and glial cells, which can replace damaged or lost cells.
-
Neuroprotection: Stem cells release various bioactive molecules that can protect neurons from further damage and promote their survival.
-
Modulation of Inflammation: Stem cells possess immunomodulatory properties that can modulate the neuroinflammatory response associated with neurodegenerative diseases, potentially slowing down disease progression.
-
Trophic Support: Stem cells release trophic factors that promote the growth, survival, and function of existing neurons, providing an environment conducive to neural repair.
While the mechanisms of action are still being investigated, these potential benefits highlight the therapeutic potential of stem cells for neurodegenerative diseases.
Challenges in Implementing Stem Cell Therapy
Despite the promising potential of stem cell therapy, several challenges need to be addressed before it can be widely implemented for neurodegenerative diseases. These challenges include:
