Other symptoms might seem a little unusual — for instance, TBI patients sometimes struggle with repeated episodes of vomiting or have one pupil larger than the other. Still other symptoms are subtle and may appear to be entirely unrelated to the injury — for instance, some people with TBI experience heightened levels of anxiety, depression and mood swings. When traumatic brain injuries cause psychiatric symptoms.
In , a group of Danish scientists found that individuals with TBI including concussions were four times more likely to develop a mental illness.
How head injuries lead to serious brain diseases
People who had received a TBI were 65 percent more likely to develop schizophrenia , 59 percent more likely to develop depression and 28 percent more likely to develop bipolar disorder. This study is the largest of its kind and involved following 1. This study is far from the only one to suggest a link between TBI and mental illness. A research team led by Jonathan Godbout, an associate professor at Ohio State University, found that mice that had sustained a TBI demonstrated increased depressive symptoms as well as higher-than-normal levels of neural inflammation. Yet another study found that experiencing depressive symptoms after a head injury is more common than not — the prevalence of depression after TBI is greater than 50 percent.
Traumatic Brain Injury: Hope Through Research
The most frightening piece of research, however, was published earlier this year: People who had received a concussion in the past were three times more likely to fall victim to suicide. Many of them had received only mild concussions and treated them in the way most people treat concussions: a short visit to the emergency room, bed rest and painkillers. They were not war veterans or football players. They were individuals who left a car accident with just a headache and a sore neck, or student athletes who underestimated the speed of a baseball.
The brain is a delicate organ and, unfortunately, it does not take much to knock its chemistry out of alignment. As a doctor, I repeatedly inquire my patients about head injuries because of how common they are.
Traumatic Brain Injury
I ask not only the patients, but also their close relatives and roommates. Once, I encountered a year-old mother who presented with anxiety, depression and psychotic symptoms. Although she claimed to have never suffered any head trauma, her mother remembered that, at the age of 5, she had been in a car accident and lost consciousness for more than 30 minutes.
She later had a seizure. I placed the patient on an anticonvulsant, a drug designed to reduce seizures, and she soon reported a decrease in her symptoms. Speak with your doctor.

Traumatic brain injury TBI results from an impact to the head that disrupts normal brain function. The leading causes of TBI that resulted in emergency department visits were falls, being struck by an object and motor vehicle crashes. Indirect forces that jolt the brain violently within the skull, such as shock waves from battlefield explosions, can also cause traumatic brain injury.
In addition, traumatic brain injury can result from bullet wounds or other injuries that penetrate the skull and brain. Doctors classify traumatic brain injury as mild, moderate or severe, depending on whether the injury causes unconsciousness, how long unconsciousness lasts and the severity of symptoms. Although most traumatic brain injuries are classified as mild because they're not life-threatening, even a mild traumatic brain injury can have serious and long-lasting effects. Resulting from an impact to the head that disrupts normal brain function, traumatic brain injury is a threat to cognitive health in two ways:.

Anyone who experiences an impact to the head and develops any symptoms of traumatic brain injury should seek medical attention, even if symptoms seem mild. Seek emergency care for anyone whose head was injured during ejection from a vehicle, who was struck by a vehicle while on foot or who fell from a height of more than three feet. Falls are the most common cause of traumatic brain injury, and falling poses an especially serious risk for older adults.
According to a CDC special report analyzing data from several federal agencies, each year 56, seniors are hospitalized as a result of head injuries sustained in falls and 8, die as a result. When a senior sustains a serious traumatic brain injury in a fall, direct effects of the injury may result in long-term cognitive changes, reduced ability to function and changes in emotional health. An estimated , older adults are living with traumatic brain injury-related disability. Measures to reduce the risk of falls include: Home safety and dementia. Over the past 30 years, research has linked moderate and severe traumatic brain injury to a greater risk of developing Alzheimer's disease or another dementia years after the original head injury.
Does every hit to the head lead to dementia? Not everyone who experiences a head injury develops dementia. More research is needed to confirm the possible link between brain injury and dementia and to understand why moderate, severe and repeated mild traumatic brain injuries may increase risk. Also inform your health care professional if you drink alcohol or take illicit drugs.
If you experience a traumatic brain injury, it should be noted in your permanent medical record and mentioned whenever familiarizing a new doctor with your medical history. The most serious traumatic brain injuries require specialized hospital care and can require months of inpatient rehabilitation. Most traumatic brain injuries are mild and can be managed with either a short hospital stay for observation or at-home monitoring followed by outpatient rehab, if needed.
Treatment of dementia in a person with a history of traumatic brain injuries varies depending on the type of dementia diagnosed.
