Stroke occurs when the blood supply to the brain is blocked or reduced which causes cells in some areas of the brain died due to lack of oxygen and nutrients, therefore the body parts which are controlled by the damaged brain cannot function properly.
Causes of stroke include:
Brain tumors are abnormal tissues that arise due to abnormal cell growth in the brain. Brain tumors originating from brain cell tissue are referred to as primary brain tumors, while brain tumors originating from the spread of malignant tumors in other parts of the body to the brain are referred to as secondary tumors (metastasis).

Spondylolithesis is simply referred to as a spinal shift. In general, spondylolisthesis shows symptoms of severe pain that will get worse when it is moved. Some risk factors for spondylolisthesis include:
HERNIATED NUCLEUS PULPOSUS
Herniated Nucleus Pulposus (HNP) is a condition caused by a protrusion of the nucleus (nucleus pulposus) from the spinal cord that presses on the nerves, causing pain and weakness in the limbs associated with the pinched nerve. Symptoms that will appear depending on the location of the pinched nerve, which include:
Spondylosis is a term that refers to spinal damage due to the aging process (degeneration) of the spine. Spondylosis can occur in the Cervical (backbone near the neck), Thoracic (upper spine), and Lumbar (lower spine).
Symptoms that appear can vary depending on where the spine is affected, but in general the symptoms of spondylosis include:
