Spastic diplegia of the infantile type (SDIT) refers to a group of bone pathologies that are characterized by the development of erased spasticity in the lower limbs, affecting infants and young children. This condition is one of the most common types of cerebral palsy and is characterized by impaired motor function caused by damage to the central nervous system. The main clinical manifestations include impaired motor development, increased muscle tone, and coordination disorders. These symptoms become noticeable in early childhood and can lead to significant limitations in physical activity. It is important to note that spastic diplegia can be combined with other neurological and psychiatric disorders, which complicates diagnosis and treatment.
History of the disease and interesting historical facts
The history of spastic diplegia research dates back to the 19th century, when the Ukrainian physician Ivan Mechnikov described the first cases of cerebral palsy in children. However, systematic study of diseases of the nervous system did not begin until the early 20th century. In the 1940s, research in neurology and pediatrics led to a deeper understanding of the mechanisms underlying spastic diplegia. In the 1950s, a classification of the various forms of cerebral palsy was developed, allowing for more accurate diagnosis and treatment of the condition.
Interestingly, some of the first studies noted that neurodevelopmental delays and muscle hypertonia were observed among children with cerebral palsy. Current studies support the findings that early diagnosis and intervention significantly improve the prognosis.
Epidemiology
According to current data, the prevalence of spastic diplegia of the infantile type varies from 1.5 to 4 cases per 1000 live births. Taking into account the data for the last decades, there is a tendency for the incidence to increase, which may be associated with improved diagnostics and increased survival of premature infants. Spastic diplegia is observed in both boys and girls, but there is a tendency for a higher prevalence in boys (ratio 1.5:1).
Predictions for disease incidence indicate that approximately 20-30% children with DSIT will achieve some level of independence with comprehensive rehabilitation. It is important to consider the variety of factors that may influence the development of this disease, including perinatal and postnatal influences.
Genetic predisposition to this disease
Although spastic diplegia is not considered a strictly hereditary disease, some genetic factors may influence its development. Research indicates the involvement of various genes responsible for the development and functioning of the nervous system, including genes associated with myelination, neurogenesis, and other important neurobiological processes. Mutations in genes such as STXBP1, GNAO1, and others may increase the risk of developing clinical manifestations of spastic diplegia.
There is also a link with some syndromes that have a genetic basis, such as Angelman syndrome and Down syndrome, which may include spastic diplegia as one of their manifestations. Current genetic studies are ongoing, with the goal of gaining a deeper understanding of the molecular mechanisms underlying the pathogenesis of this disease.
Risk factors for the development of this disease
Spastic diplegia of the infantile type can be caused by many factors, and they are divided into physical and chemical. These include:
- Perinatal factors:
- Prematurity (< 28 weeks);
- Birth weight less than 1500 grams;
- Complications during childbirth, such as asphyxia or brain injury.
Chemical factors include:
- Exposure to toxic substances in the womb, including alcohol and drugs;
- Maternal infections during pregnancy, such as toxoplasmosis or cytomegalovirus;
- The mother's general health (eg, diabetes).
Other risk factors may include a range of different neurological diseases, as well as environmental factors such as social conditions and access to health care.
Diagnosis of this disease
Diagnosis of spastic diplegia of the infantile type includes several stages and requires a comprehensive approach, which significantly complicates the establishment of an accurate diagnosis. The main symptoms of spastic diplegia of the infantile type are as follows:
- Increased muscle tone in the lower limbs;
- Delayed motor development;
- Muscle weakness and uneven muscle development;
- Unusual reflexes (eg, Babinski reflex).
Laboratory tests may include blood tests to look for metabolic and genetic disorders. Radiological tests, such as magnetic resonance imaging (MRI) and computed tomography (CT) scans, may look for structural changes in the brain or other abnormalities.
Other diagnostics may include neurophysiological studies such as electroencephalography, which helps assess the level of brain activity. Other forms of cerebral palsy and neurological disorders are always excluded as differential diagnoses.
Treatment
Treatment for spastic diplegia is complex and multidisciplinary, including physical rehabilitation, pharmacological therapy, and, in some cases, surgery. General treatment involves the use of physical therapy to improve muscle mobility and strength, as well as posture correction and training in proper movement patterns.
Pharmacological treatment may include drugs that reduce muscle tone, such as baclofen or thiopental. In cases where conservative therapy is ineffective, surgical treatment is indicated, including botulinum therapy to temporarily reduce spasticity.
In addition, alternative methods such as acupuncture and psychotherapy techniques may be used to improve neurological status and adaptation to life with the disease.
List of medications used to treat this disease
- Baclofen;
- Sodium thiopental;
- Dantrolene;
- Botulinum toxin type A;
- Selegiline;
- Riluzole.
These drugs can be used either in combination with physical therapy or as a stand-alone treatment depending on the clinical situation.
Disease monitoring
Monitoring of a child with spastic diplegia includes periodic assessment of motor and neurological development. Control stages should be carried out at least once every six months to adapt treatment and rehabilitation approaches.
The prognosis for spastic diplegia of the infantile type varies. Many children are able to achieve a level of independence in locomotion, but complications such as skeletal deformities and problems with self-care may occur, requiring additional correction and intervention.
Age-related features of the disease
Spastic diplegia can present differently depending on the age of the child. In infancy, signs include:
- Slow motor development;
- Observation of increased tone in the lower extremities;
- Problems with the joint activity of the upper and lower limbs.
As the child grows and matures, features such as:
- Increased dependence on people around you;
- Inability to perform complex movements in living conditions;
- Development of pronounced spasticity in the absence of rehabilitation.
Early detection and intervention can improve quality of life and motor function.
