Current Trends in the Treatment of Neurodegenerative Diseases

Neurodegenerative diseases, such as Alzheimer’s, Parkinson’s and multiple sclerosis, are conditions that affect the central nervous system and involve the progressive loss of neurons. In recent years, innovations in advanced neurorehabilitation have been revolutionizing treatment, from the use of artificial intelligence to assistive technologies. This article explores the latest trends in neurorehabilitation, from the use of artificial intelligence to digital therapies, and how these innovations are transforming the treatment of neurodegenerative diseases.

The importance of advancing research and treatment of neurodegenerative diseases

In recent years, the treatment of neurodegenerative diseases has experienced significant advances. Thanks to the combination of innovative technology and modern therapeutic approaches, people with these conditions have access to personalized neurorehabilitation interventions that improve their quality of life. 

This progress in treatments for neurodegenerative diseases, such as Alzheimer’s or Parkinson’s, is crucial on multiple levels. Not only to improve the quality of life of those who suffer from them, but also to relieve the emotional and financial burden these conditions represent for families, caregivers, and health systems worldwide. 

As research advances, new therapies and technologies are emerging, offering hope to millions of affected people. 

Main trends in neurorehabilitation for neurodegenerative diseases 

1. Early diagnosis of neurodegenerative diseases through neuromarkers

Early diagnosis of neurodegenerative diseases such as Alzheimer’s, Parkinson’s and the multiple sclerosis is key to improving the lives of people who suffer from them, since it offers a unique window of opportunity to intervene and slow the disease process. 

In order to achieve this early diagnosis, one of the current trends is the use of neuromarkers in neurorehabilitation to identify the first signs of these conditions before clinical symptoms become more evident. 

What are neuromarkers?

Neuromarkers are biological indicators that allow detection of structural and functional changes in the brain related to neurodegenerative diseases. These signals can be identified using advanced technologies such as functional magnetic resonance imaging (fMRI) and positron emission tomography (PET).

Neuromarkers most commonly used in the early diagnosis of neurodegenerative diseases 

1. Tau and beta-amyloid proteins in Alzheimer’s disease

The combination of these two biomarkers is one of the most reliable methods to predict the development of Alzheimer’s disease in individuals with mild cognitive impairment before the disease progresses to a more severe stage.

Abnormal deposits of beta-amyloid and tau in the brain are early indicators of Alzheimer’s disease and help predict disease progression. The accumulation of these plaques begins years before the clinical symptoms of the disease become evident. 

2. Alpha-synuclein in Parkinson’s disease and other related disorders such as multiple system atrophy

Alpha-synuclein is a protein associated with neurodegenerative diseases such as Parkinson’s disease, dementia with Lewy bodies, and multiple system atrophy (MSA). In these disorders, alpha-synuclein accumulates abnormally in the brain, forming toxic aggregates that disrupt neuronal function, damaging dopaminergic neurons and affecting both motor and cognitive abilities.

Altered levels of alpha-synuclein in cerebrospinal fluid can help distinguish between Parkinson’s disease and other pathologies such as multiple system atrophy or dementia with Lewy bodies, as well as detect the disease in early stages.

3. Neuroinflammation biomarkers in multiple sclerosis (MS) and other inflammatory diseases of the central nervous system 

Neuroinflammation plays a crucial role in the development of many neurodegenerative diseases, including multiple sclerosis. Inflammatory biomarkers, such as cytokines (proteins involved in cell communication), can be measured in cerebrospinal fluid or blood to detect inflammation in the brain and spinal cord.

One example of these inflammatory markers is the axonal damage protein called neurofilament light chain (NFL), used to measure damage and neuronal degeneration in multiple sclerosis. This marker is elevated when there is active inflammation or neuronal damage, and allows clinicians to assess the risk of relapses or disease progression.

Detecting inflammation through these markers is useful not only for diagnosing multiple sclerosis in early stages, but also for monitoring disease activity and adjusting treatments based on each person’s response.

Benefits of neuromarkers in the neurorehabilitation of neurodegenerative diseases 

The use of neuromarkers in neurorehabilitation allows neurorehabilitation professionals to:

• design more precise and tailored interventions for each person,
• and improve the ability to assess response to cognitive, physical, and occupational rehabilitation therapies.

2. Personalized therapies in the treatment of neurodegenerative diseases 

In neurorehabilitation, therapy personalization has become one of the best practices for delivering treatments for neurodegenerative diseases such as Alzheimer’s, Parkinson’s, or multiple sclerosis. 

What is therapy personalization?

Personalizing therapies involves designing specific interventions based on the individual characteristics of each person, their needs, and their particular processes in order to slow the progression of these pathologies and optimize therapeutic outcomes.

Tools for personalizing therapies in neurodegenerative diseases 

1. Detailed neuropsychological assessments

The cognitive and emotional assessments in those affected by Alzheimer’s or Parkinson’s allow identification of areas affected by the disease. These tests help therapists design personalized interventions that address specific deficits, such as memory, language, or attention.

2. Artificial intelligence (AI)

AI has become a key tool in neurorehabilitation. By analyzing large volumes of clinical data, the AI algorithms can predict how a person will respond to different interventions, allowing professionals to adapt therapies based on expected outcomes.

3. Real-time monitoring devices

Wearable devices that measure physical activity and cognitive responses allow therapists to adjust therapies on the fly. This is especially useful in diseases such as Parkinson’s or multiple sclerosis, where the condition of each affected person can change significantly in a short time.

Benefits of therapy personalization in the neurorehabilitation of neurodegenerative diseases 

The use of personalized therapies in neurorehabilitation for neurodegenerative diseases offers multiple benefits, both for the people who suffer from these conditions and for healthcare professionals:

• Greater therapeutic effectiveness: Adapting interventions to the specific needs of each person improves the effectiveness of therapies and optimizes long-term outcomes.
• Improved quality of life: Affected individuals experience significant improvements in their quality of life when receiving therapies that are tailored to their abilities and individual limitations.
• More precise monitoring: Personalization also involves continuous monitoring of each affected person’s progress, allowing therapies to be adjusted in real time as needed.

3. Use of assistive technology in neurodegenerative diseases 

In recent years, the use of assistive technology has transformed the field of neurorehabilitation, especially in the treatment of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, multiple sclerosis (MS), and the amyotrophic lateral sclerosis (ALS).

What is assistive technology?

Assistive technology encompasses a wide range of devices, software and equipment designed to support people with physical and cognitive disabilities or limitations. In the context of neurorehabilitation, these devices are used to compensate for motor and cognitive functions affected by neurodegenerative diseases, facilitating each person’s autonomy and optimizing rehabilitative treatment.

Assistive technology tools in neurodegenerative diseases

1. Virtual and augmented reality 

Virtual reality (VR) has proven to be effective for cognitive and motor rehabilitation in people with Alzheimer’s and other neurodegenerative diseases, improving their neuroplasticity and learning ability.

2. Cognitive rehabilitation software 

Digital neurorehabilitation platforms, like NeuronUP, allow users to work with activities designed to improve their improvement, language, and other cognitive functions affected by neurological impairment.

Benefits of using assistive technology in the neurorehabilitation of neurodegenerative diseases 

The use of assistive technology in the neurorehabilitation of these types of pathologies allows: 

• Improved mobility and independence: Assistive devices, such as exoskeletons and smart walkers, enable people with Parkinson’s or multiple sclerosis (MS) to improve their mobility, which reduces dependence on caregivers and facilitates the performance of daily activities.
• Personalized cognitive stimulation: Tools such as mobile applications and virtual reality programs are used to design personalized cognitive rehabilitation exercises. These technologies are particularly useful in the treatment of Alzheimer’s, helping to improve memory, attention, and executive functions.
• Real-time health monitoring: Tracking devices and wearables allow healthcare professionals to monitor vital signs, physical activity, and therapeutic progress of affected individuals in real time. This is essential to adjust therapies based on the evolution of diseases such as amyotrophic lateral sclerosis (ALS).
• Augmented communication: Assistive communication technologies, such as speech-generating devices, enable people with ALS and other neurodegenerative conditions to improve their ability to interact with their environment, despite physical or speech limitations.

4. Multidisciplinary approaches in the neurorehabilitation of neurodegenerative diseases 

Currently, one of the most innovative and effective approaches in the neurorehabilitation of neurodegenerative diseases is the multidisciplinary approach. 

What is a multidisciplinary approach?

The multidisciplinary approach in neurorehabilitation combines the expertise and knowledge of neuropsychologists, physical therapists and other rehabilitation specialists, allowing a comprehensive approach that optimizes the treatment of neurodegenerative diseases such as Alzheimer’s and Parkinson’s. 

Benefits of the multidisciplinary approach in the neurorehabilitation of neurodegenerative diseases 

Adopting a multidisciplinary approach in neurorehabilitation for neurodegenerative diseases offers multiple benefits to affected individuals and professionals: 

• Comprehensive and personalized treatment: The collaboration of multiple specialists allows each affected area to be addressed specifically, ensuring a treatment tailored to each person’s unique needs and achieving better outcomes.
• Improved neuroplasticity: By stimulating the brain from different areas, the capacity for neural adaptation and reorganization is enhanced, resulting in better functional recovery and compensation for progressive damage.
• Delay in symptom progression: Coordinated interventions can slow symptom progression, especially in cognitive and functional areas, allowing people affected by neurodegenerative diseases to maintain their autonomy for longer.

Conclusions

Current trends in the treatment of neurodegenerative diseases demonstrate a wholehearted commitment to improving quality of life and prognosis for people with these conditions.

Early diagnosis allows for earlier and more effective intervention, while personalized therapies open the door to treatments tailored to each person’s characteristics, thus optimizing outcomes.
