What is Central cord syndrome and explain in detail?
Central cord syndrome (CCS) is the most common form of cervical spinal cord injury. It is characterized by loss of motion and sensation in arms and hands. It usually results from trauma which causes damage to the neck, leading to  major injury to the central corticospinal tract of the spinal cord.  The syndrome is more common in people over the age of 50 because osteoarthritis in the neck region causes weakening of the vertebrae. CCS most frequently occurs among older persons with cervical spondylosis, however, it also may occur in younger individuals.CCS is the most common incomplete spinal cord injury syndrome. It accounts for approximately 9% of traumatic SCIs.  After an incomplete injury, the brain still has the capacity to send and receive some signals below the site of injury. Sending and receiving of signals to and from parts of the body is reduced, not entirely blocked. CCS gives a greater motor loss in the upper limbs than in the lower limbs, with variable sensory loss.
It was first described by Schneider in 1954.  It is generally associated with favorable prognosis for some degree of neurological and functional recovery. However, factors such as age, preexisting conditions, and extent of injury will affect the recovery process.

Presentation
CCS is characterized by disproportionately greater motor impairment in upper compared to lower extremities, and variable degree of sensory loss below the level of injury in combination with bladder dysfunction and urinary retention. This syndrome differs from that of a complete lesion, which is characterized by total loss of all sensation and movement below the level of the injury.

Causes
In older patients, CCS most often occurs after acute hyperextension injury in an individual with long-standing cervical spondylosis. A slow, chronic cause in this age group is when the cord gets caught and squeezed between a posterior intervertebral disc herniation against the anterior cord and/or with posterior pressure on the cord from hypertrophy of the ligamentum flavum (Lhermittes sign may be the experience that causes the patient to seek medical diagnosis). However, CCS is not exclusive to older patients as younger individuals can also sustain an injury leading to CCS. Typically, younger patients are more likely to get CCS as a result of a high-force trauma or a bony instability in the cervical spine. Historically, spinal cord damage was believed to originate from concussion or contusion of the cord with stasis of axoplasmic flow, causing edematous injury rather than destructive hematomyelia. More recently, autopsy studies have demonstrated that CCS may be caused by bleeding into the central part of the cord, portending less favorable prognosis. Studies also have shown from postmortem evaluation that CCS probably is associated with selective axonal disruption in the lateral columns at the level of the injury to the spinal cord with relative preservation of the grey matter.

Diagnosis
Management
Nonsurgical
In many cases, individuals with CCS can experience a reduction in their neurological symptoms with conservative management. The first steps of these intervention strategies include admission to an intensive care unit (ICU) after initial injury
