T90: Sequelae of injuries of head

The Sequelae of injuries of head is a group of conditions that are the after-effects or secondary results from any form of head injury. These conditions can develop immediately or even long after the initial injury. The sequelae can be a direct result from the injury, such as a fracture causing chronic pain, or an indirect effect like a traumatic brain injury leading to cognitive impairment. Symptoms vary widely, ranging from physical problems such as headaches and dizziness to emotional, behavioral, and cognitive issues such as depression, irritability, memory problems, and difficulty concentrating. Disease progression depends on the severity and type of the initial head injury. The central nervous system, including the brain and cranial nerves, is primarily affected by these conditions. It's important to note that not everyone who experiences a head injury will develop a sequlalae condition, but the risks increase with the severity of the injury.
