Common Neurological Disorders and Orthopedic Challenges

Introduction:

The primary function of the neural system in the human body is to maintain coordination. The nerves and organs of the nervous system not only maintain balance among the internal organs and help maintain coordination with the outside world. Even functions like locomotion are regulated by the nervous system. That is why nerves and the nervous system are essential to orthopedic health. However, several neurological disorders may cause severe orthodontic complications.

What Are the Effects of Common Neurological Diseases on Orthepredic Health?

Neurological diseases are disorders that cause poor functioning of the various parts of the nervous system.

These conditions include;

Autism Spectrum Disorder: Autism or autism spectrum disorders are a group of neurodevelopmental disorders mainly observed in children and young individuals. Abnormalities in brain development often cause this developmental disorder. This affects the child's emotional, social, cognitive, and physical development.

Abnormalities in the brain's anatomical structure, such as cerebellar architecture and connectivity abnormalities, limbic system abnormalities, frontal and temporal lobe dysfunction, and cortical alterations, cause this.

Risk factors for such conditions include genetic mutations, metabolic disorders like phenylketonuria (a disorder of amino acid metabolism), Smith-Lemli-Opitz syndrome (cholesterol metabolism disorders), dihydrofolate reductase deficiency (disorders of cerebral folate), and infections in childhood.

The orthopedic problems associated with autism include;

• Autistic children often show poor bone quality. This is mainly caused by poor nutrition, increased IGF-1 (insulin-like growth factor 1, a hormone associated with growth), and defective vitamin D metabolism. As a result, patients show poor bone marrow density, poor strength of the bone, and poor development of the bones.

• Autistic children are prone to developing pathologic fractures in the joints.

• Due to a lack of development and poor neuromuscular control, muscle mass loss and poor muscle strength are observed.

• Antipsychotic therapies (APTs) are also responsible for poor bone development. Apart from this, metabolic disorders cause dysregulation in mineral metabolism.

Cerebral Palsy: Cerebral palsy is a group of motor disorders that affect the normal functioning of nerves, muscles, and neuromuscular functions due to the immaturity of brain and nerve lesions. These group disorders are permanent and cause developmental and functional impairments. A genetic alteration in the RHOB, FBXO31, DHX32, and ALK genes causes this condition. Infections caused by cytomegalovirus (CMV), rubella (German measles), chickenpox, and toxoplasmosis (a parasitic infection) may also be responsible for this.

The orthopedic complications related to cerebral palsy are;

• Neuromuscular abnormalities are the main complication associated with this. Patients often show complications like poor neuromuscular coordination, hyperreflexia, unusual muscle contraction, and abnormal muscle tightness or spasticity.

• Brain and spinal cord abnormalities cause problems in walking, running, standing, and holding things.

• Overall developmental depreciation results in poor muscle development, loss of muscle mass, and poor muscle strength.

• Poor bone health in such cases includes poor bone marrow density, osteoporosis (loss of minerals from bone), and poor bone strength. This is caused by multiple factors, including nutritional dysfunctions, poor growth due to hormonal imbalance, and side effects of drugs like anticonvulsants.

Alzheimer’s Disease: Alzheimer’s disease is a neurological disorder that is responsible for the loss of brain functions. It is characterized by the degeneration and death of neurons and nerve cells within the brain. The primary cause of this degeneration is the accumulation of amyloid-beta peptide plaques in the brain. Genetic involvement and aging, which cause glucose hypometabolism, cholesterol dyshomeostasis (irregularity in cholesterol metabolism), mitochondria dysfunction, and cognitive decline, are responsible for this.

The orthopedic challenges associated with this are;

• The most common orthopedic problem associated with Alzheimer’s patients is low bone mineral density and osteoporosis. The causative factors related to these are genetic involvement and metabolic dysfunction.

• Defective neural signaling and parasympathetic activity are also associated with poor bone formation. These signaling systems are responsible for osteoblasts' poor functioning and bone turnover.

• Certain genetic involvement causes Nasu–Hakola disease (explain) in Alzheimer’s patients. Bone cysts, bone fractures, and dysplastic changes in the bone characterize this condition.

Parkinson’s Disease: Parkinson's disease is a progressive neurodegenerative condition that results in the loss of dopamine-producing cells in the brain, causing both motor and non-motor symptoms, including tremors, rigidity, and impaired balance and coordination. It primarily affects the motor system and is estimated to affect around one million people in the United States. The reduced dopamine production in the brain cells significantly contributes to this condition, which affects the central nervous system and results in excessive muscle movements and tremors.

The orthopedic challenges related to this are;

• Uncoordinated muscle movements and loss of muscle functions cause muscular atrophy, muscle mass loss, and muscle strength loss.

• Change in posture and gait is evident. Also, people gradually lose the ability to walk, stand, and run alone.

• Neurotransmitter dysregulation is also associated with endocrine dysfunction. Complications such as hyperparathyroidism are related to mineral dysregulation and vitamin D deficiency, which can cause poor bone health.

• Nutritional deficiency and metabolic problems due to brain dysfunction cause poor bone mineral density and poor bone strength.

How to Overcome Orthopedic Challenges in Neurological Disorders?

Various measures can be taken to overcome orthopedic challenges related to neurological disorders.

These are,

1. Regular exercise is one of the most important ways to improve bone and muscle health. Strength training is helpful in improving muscle strength and mass. Stretching is useful for improving muscle functioning and joint flexibility. These exercises also prevent any type of muscle or tendon injury.

2. Aerobic exercises are useful in improving overall health and cardiorespiratory performance. They also improve blood flow, metabolic function, and hormonal balance.

3. Diet plays a vital role in maintaining nutrition and mineral balance.

4. Calcium and vitamin D supplements can also improve bone health. They can prevent osteoporosis and improve bone marrow density.

Conclusion:

Neurological disorders cause a significant loss of muscle function and coordination, which is related to the loss of normal functions like walking and running. They also often cause poor bone strength and reduced bone marrow density. Regular exercise and a proper diet are helpful in such cases.
