Warning Signs Of Chiari Malformation

Issues Breathing

Chiari malformation occurs when parts of an individual's brain protrude down into their central spinal canal. Breathing requires the cooperation of several parts of an individual's brain. The brainstem and cerebellum both play critical roles in the autonomous part of breathing. The pons is responsible for bridging the various parts of the brain that control several vital functions. The lower sections of an individual's pons are responsible for regulating breathing intensity. The upper sections of the pons regulate the frequency and depth of an individual's breaths. The medulla, which is part of the hindbrain, manages the involuntary part of breathing. When Chiari malformation causes any of these parts of the brain to become compressed, individuals will experience breathing problems.

Poor Coordination

The cerebellum puts together the sequence of movements and then implements them. Other parts of the brain are involved in the movement coordination process. However, the cerebellum is responsible for most of this function, along with posture and balance. When the cerebellum becomes damaged due to excessive pressure, the individual will have trouble controlling the position of their legs, arms, and posture.

Chiari malformation patients can sustain extensive damage to parts of their cerebellum as it inappropriately extends down into the increasingly narrow spinal canal. The medical terms used to describe these problems with coordination are known as dysmetria and ataxia. Poor coordination may or may not be isolated to a patient's posture and limbs when it is caused by Chiari malformation.
