Developmental Motor Coordination Disorder (DMCD) is a neurodevelopmental condition that affects a person’s ability to perform everyday tasks that require coordinated movements.
It is characterized by difficulties in motor skills, coordination, and balance. Individuals with DMCD often struggle with activities such as tying shoelaces, writing, or participating in sports. In this article, we will explore the causes of DMCD and delve into the various factors that contribute to its development.
Genetic Factors
Research suggests that genetic factors play a significant role in the development of DMCD. Studies have shown that individuals with a family history of motor coordination difficulties are more likely to develop the disorder.
Certain genes related to motor control and coordination have been identified as potential culprits in DMCD. Genetic mutations or variations in these genes can disrupt the normal development of motor pathways in the brain, leading to motor coordination difficulties.
Neurological Factors
The human brain plays a vital role in motor coordination. Any disruption or abnormality in the brain’s structure or function can contribute to the development of DMCD.
Neurological conditions such as cerebral palsy, attention deficit hyperactivity disorder (ADHD), and autism spectrum disorders are often associated with motor coordination difficulties. These conditions can affect the brain’s ability to send and receive signals necessary for coordinated movements.
Developmental Delays
Children who experience developmental delays, particularly in areas related to motor skills, are at a higher risk of developing DMCD.
These delays could be due to various factors, including premature birth, low birth weight, prenatal exposure to toxins, or maternal substance abuse. When children do not reach certain developmental milestones, it can indicate underlying issues with motor coordination, which may later manifest as DMCD.
Sensory Processing Issues
Sensory processing refers to the brain’s ability to interpret and respond to information received through the senses.
Individuals with DMCD often have difficulties in processing sensory information, such as touch, proprioception, and vestibular sensations. An inefficient sensory processing system can disrupt the coordination of movements, as it affects the integration of sensory feedback necessary for motor control.

Environmental Factors
Environmental factors can also contribute to the development of DMCD.
Lack of opportunities for physical activity, inadequate stimulation of motor skills during early childhood, and limited access to appropriate therapies can hinder the development of motor coordination. Additionally, exposure to high levels of stress or trauma during critical periods of development can interfere with the normal maturation of motor pathways.
Anxiety and Psychoemotional Factors
Anxiety and psychoemotional factors can impact an individual’s motor coordination abilities.
High levels of anxiety, stress, or emotional disturbances can interfere with concentration, attention, and motor planning, leading to difficulties in motor coordination. In some cases, individuals with DMCD may develop secondary psychological issues, such as low self-esteem or social anxiety, due to their motor coordination difficulties.
Motor Skill Acquisition Challenges
Children with DMCD often experience challenges when acquiring new motor skills. They may require additional practice and instruction to develop skills that their peers can acquire effortlessly.
These difficulties may lead to frustration and avoidance of activities that demand high levels of coordination. Lack of practice and avoidance can further perpetuate motor coordination deficits.
Treatment Approach
Treating DMCD involves a multidisciplinary approach that addresses the underlying causes and helps individuals develop compensatory strategies. Occupational therapy, physical therapy, and speech therapy can be beneficial in improving motor coordination.
Additionally, emotional support and counseling can help individuals overcome psychological barriers associated with DMCD.
Conclusion
Developmental Motor Coordination Disorder can significantly impact an individual’s daily functioning and quality of life.
While the exact causes of DMCD are not completely understood, a combination of genetic, neurological, developmental, sensory, environmental, and psychoemotional factors contribute to its development. Early identification and intervention are crucial in minimizing the long-term impacts of DMCD and improving functional outcomes for individuals affected by this condition.
