In the United States, head injuries are one of the most common causes of death and disability. Head injuries due to bleeding are generally classified by the location of the blood within the skull, these include:
- epidural hematoma,
- subdural hematoma,
- subarachnoid bleed,
- intracranial bleed,
- sheer injury, edema, and
- skull fracture.
Some common symptoms of a head injury include:
- bleeding from the ear,
- speech difficulties,
- difficulty swallowing, and
- body numbness.
Treatment of a head injury depends on the type and severity of the injury.Read more: Head Injury (Brain Injury) Article

Related Disease Conditions
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
A hematoma is a collection of blood that is outside a blood vessel. There are different areas where hematomas occur including: inside the skull, scalp, ear, septum, bones, finger and toenails, and intra-abdominal. Treatment for hematomas depend on the type and location of the hematoma.
Pulmonary edema (swelling or fluid in the lungs) can either be caused by cardiogenic causes (congestive heart failure, heart attacks, abnormal heart valves) or noncardiogenic causes such as: ARDS, kidney failure, high altitude, pneumothorax, pleural effusion, aspirin overdose, pulmonary embolism, and infections. The treatment of pulmonary edema depends on the cause of the condition.
Brain aneurysm (cerebral aneurysm) is caused by microscopic damage to artery walls, infections of the artery walls, tumors, trauma, drug abuse. Symptoms include headache, numbness of the face, dilated pupils, changes in vision, the "worst headache of your life," or a painful stiff neck. Immediate treatment for a brain aneurysm is crucial for patient survival.
A brain hemorrhage is a type of stroke caused when an artery bursts in the brain, causing localized bleeding in the surrounding tissue. Causes of brain hemorrhage include aneurysm, liver disease, brain tumor, head trauma, high blood pressure, and blood vessel abnormalities. Symptoms include sudden severe headache, nausea, vomiting, loss of balance, tingling, numbness, vision changes, loss of consciousness, and loss of fine motor skills. Treatment depends upon the cause, location, and size of the brain hemorrhage.
14 Signs and Symptoms of Stroke (FAST)
Stroke is a serious medical condition. If you think you or someone you know is having a stroke call 911 immediately. There are two main types of strokes, hemorrhagic and ischemic (the most common type). A hemorrhagic stroke occurs due to a blood vessel rupture in the brain. An ischemic stroke occurs when a blood clot becomes lodged in a blood vessel in the brain, which causes a loss of blood supply to the brain, possibly causing brain tissue death. FAST is an acronym that helps people identify stroke signs and symptoms so they can act fast and call 911. Face drooping, Arm weakness, and Speech difficulty are indicators that a person may be having a stroke and it is Time to seek emergency medical treatment. Additional signs and symptoms of stroke may include weakness, difficulty walking, blurred vision, dizziness, headache, confusion, difficulty speaking, and loss of sensation. Stroke is a major cause of death and disability in the U.S. Early identification and treatment of stroke helps reduce the risk of morbidity and mortality.
Internal bleeding occurs when an artery or vein is damaged and blood to escapes the circulatory system and collects inside the body. Internal bleeding can be caused by a variety of situations such as blunt trauma, deceleration trauma, medications, fractures, and spontaneous bleeding. Treatment of internal bleeding depends on the cause of the bleeding.
Fainting (Syncope) Symptoms, Causes, Treatment, and Prevention
Fainting, also referred to as blacking out, syncope, or temporary loss of consciousness has many causes. Often a person will have signs or symptoms prior to the fainting episode. Diagnosis and treatment depends upon the cause of the fainting or syncope episode.
Blood Clots (In the Leg)
Blood clots can occur in the venous and arterial vascular system. Blood clots can form in the heart, legs, arteries, veins, bladder, urinary tract and uterus. Risk factors for causes of blood clots include high blood pressure and cholesterol, diabetes, smoking, and family history. Symptoms of a blood clot depend on the location of the clot. Some blood clots are a medical emergency. Blood clots are treated depending upon the cause of the clot. Blood clots can be prevented by lowering the risk factors for developing blood clots.
Medical shock is a life-threatening medical condition. There are several types of medical shock, including: septic shock, anaphylactic shock, cardiogenic shock, hypovolemic shock, and neurogenic shock. Causes of shock include: heart attack, heart failure, heavy bleeding (internal and external), infection, anaphylaxis, spinal cord injury, severe burns, chronic vomiting or diarrhea. Low blood pressure is the key sign of sock. Treatment is dependant upon the type of shock.
Seizures Symptoms and Types
Seizures are divided into two categories: generalized and partial. Generalized seizures are produced by electrical impulses from throughout the brain, while partial seizures are produced by electrical impulses in a small part of the brain. Seizure symptoms include unconsciousness, convulsions, and muscle rigidity.
Nausea and Vomiting (Causes, Natural Remedies, Diet, Medication)
Nausea is an uneasiness of the stomach that often precedes vomiting. Nausea and vomiting are not diseases, but they are symptoms of many conditions. There are numerous cases of nausea and vomiting. Some causes may not require medical treatment, for example, motion sickness, and other causes may require medical treatment by a doctor, for example, heart attack, lung infections, bronchitis, and pneumonia. Some causes of nausea and vomiting may be life threatening, for example, heart attack, abdominal obstruction, and cancers. Treatment of nausea and vomiting depends upon the cause.
The most common cause of a black eye a trauma injury to the face or head. Most black eyes are minor and heal on their own; however, some may lead to significant injury. In addition to trauma to the face, cosmetic surgery can cause a black eye(s) as a side effect. People should be aware of the situations in which medical care should be sought immediately for a black eye.
Brain Lesions (Lesions on the Brain)
A brain lesion is defined as an area of damaged brain. Brain lesions (lesions on the brain) are caused by: trauma, inflammation, autoimmune diseases, cancers, other diseases, stroke, bleeding, pituitary adenomas, and cerebral palsy. Symptoms of brain lesions include headache, nausea, fever, neck pain and stiffness, affected vision and speech, and weakness or paralysis to one side of the body. Diagnosis of brain lesions is generally accomplished with imaging studies like CT or MRI scans. Treatment and prognosis of brain lesions depends on the cause of the lesion.
Hemophilia is defined as one of a group of inherited bleeding disorders. Hemophilia A and hemophilia B are inherited in an X-linked recessive genetic pattern. Symptoms of hemophilia include bleeding into the: joints, muscles, GI or urinary tract, or brain or skull. Hemophilia treatment generally involves the replacement of blood clotting factors.
Epilepsy is a brain disorder in which the person has seizures. There are two kinds of seizures, focal and generalized. There are many causes of epilepsy. Treatment of epilepsy (seizures) depends upon the cause and type of seizures experienced.
Bell's Palsy (Facial Nerve Problems) Paralysis Causes and Treatments
Bell's palsy is one type of facial nerve paralysis. The 7th cranial nerve controls the muscles of the face, and although scientists do not know the exact cause of Bell's palsy, they think it may be due to nerve damage from an infection, for example, the flu, common cold viruses, and more serious infections like meningitis. The symptoms of Bell's palsy vary from person to person, but can include mild weakness to total paralysis, dry eye, dry mouth, eyelid drooping, drooling, mouth drooping, dry mouth, changes in taste, and excessive tearing in one eye. People with Bell's palsy usually don't need medical treatment, however, drugs like steroids, for example, prednisone seem to be effective in reducing swelling and inflammation are used when medical is necessary. Most people with Bell's palsy begin to recover within two weeks after the initial onset of symptoms. Full recovery may take three to six months.
Cauliflower ear, or "Boxer's Ear" is caused by an injury to the ear, usually by blunt trauma from sports such as boxing, wrestling, or martial arts. When hematomas form, infection, and ear drum injury may occur in addition to hearing loss if not treated. Treatment goals are to drain blood from hematomas, treat infection, and at times antibiotics to prevent further infection.
Seizure vs. Seizure Disorders (Differences and Similarities)
The differences between a seizure, epilepsy, and seizure disorders are confusing to many people. What makes it more confusing, is that they are not the same thing. A seizure begins suddenly, and is a symptom of another disease. When a seizure occurs there is uncontrolled activity in the brain that usually only lasts for a short period. While a seizure disorder is a medical condition, in which the person has episodes of uncontrolled activity in the brain producing symptoms that include one or more seizures. Epilepsy is considered a seizure disorder.There are two types of major seizures, generalized and partial seizure type and the symptoms depend upon the part of the brain affected, and may include: Loss of consciousness Thought disturbances Convulsions Eye rolling Stiff limbs Twitching on only one side or a portion of the body like an arm or leg. Involuntary urination or bowel movement Repetitive shaking or jerking of the body Staring into space, sometimes with eye blinking No loss of consciousness, but the person becomes confused for a few minutes A third type of seizure is called unclassified seizure.Seizure disorders are classified under two types of major seizures (generalized and partial), and a third type called unclassified seizures. There are about 40 types of named seizure disorders. The symptoms and signs are different depending on the part of the brain affected by the seizure. Examples of seizure disorders are: Febrile seizures Benign Rolandic epilepsy Catamenial epilepsy Absence seizures Frontal lobe epilepsy Epilepsy Sometimes there is a known cause for a seizure like alcohol, cocaine or other illegal drug abuse, drug reactions, a severe chemical imbalance in the blood, or medical problems like low blood pressure. Treatment, management, and prevention of seizures include medication and avoiding any known causes or common triggers. REFERENCES: CDC. "Types of Seizures." Updated: Apr 10, 2017.Harvard Health Publications; Harvard Medical School. "Generalized Seizures (Grand Mal Seizures)."
Newborn Jaundice (Neonatal Jaundice)
Jaundice in newborns and babies (neonatal jaundice) usually occurs because of a normal increase in red blood cell breakdown and the fact that their immature livers are not efficient at removing bilirubin from the bloodstream. Symptoms of jaundice are fever, poor feeding, and looking ill. Newborn jaundice is very common and is caused because the newborns liver isn’t mature enough to remove bilirubin from the blood. Treatment of jaundice in newborns include phototherapy, tanning booths, and other treatments.
Approximately 40 million children suffer abuse every year around the world, and more than 1,500 children die of abuse in the U.S. every year. Symptoms and signs of child abuse include poor school performance, physical injuries, regression, anxiety, and panic. Treatment involves ensuring the safety of the child and tending to any physical injuries.
Alzheimer's disease is a common cause of dementia. Symptoms and warning signs of Alzheimer's disease include memory loss, difficulty performing familiar tasks, disorientation to time and place, misplacing things, and more. The biggest risk factor for Alzheimer's disease is increased age. Treatment for Alzheimer's is often targeted toward decreasing the symptoms and progression of the disease.
Hypersomnia is a condition where a person has excessive daytime sleepiness and trouble staying awake during the day. Treatment for hypersomnia includes medication, CPAP machines, and lifestyle changes.
Concussion is a short-lived loss of brain function that is due to head trauma. There are two types of concussion, simple and complex. Symptoms of concussion include headache, nausea, dizziness, dazed feeling, irritability, visual symptoms. Physical signs include poor concentration, emotional changes, slurred speech, and personality changes. Concussion is diagnosed with physical examination and testing. Treatment for concussion in general are treatment for control of the symptoms, and time.
Stuttering is a speech disorder characterized by speech disruptions such as prolongations of speech sounds, syllables or words, frequent repetitions, or the inability to start a word. Over 3 million Americans stutter, and boys are more likely to stutter than girls. Stuttering may be developmental, neurogenic, psychogenic, or even genetically determined. Treatment for stuttering may incorporate stuttering therapy with a speech-language pathologist and educating the parents about restructuring the child's speaking environment.
Psychotic disorders are a group of serious illnesses that affect the mind. Different types of psychotic disorders include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, shared psychotic disorder, delusional disorder, substance-induced psychotic disorder, paraphrenia, and psychotic disorders due to medical conditions.
Brain Damage: Symptoms, Causes, Treatment
Brain damage causes destruction or deterioration of brain cells. Traumatic brain injury (TBI) and acquired brain injury (ABI) are two kinds of brain damage. Symptoms may include headaches, confusion, memory problems, nausea, and more. Treatment includes patient stabilization and ensuring that blood and oxygen are flowing to the brain. Adequate blood pressure control is also necessary. In cases of severe brain damage, surgery and rehabilitation may be required.
Idiopathic Thrombocytopenic Purpura (ITP)
Idiopathic means that the cause of the condition isn't known. Thrombocytopenic means there's a lower than normal number of platelets in the blood. Purpura refers to purple bruises caused by bleeding under the skin. Idiopathic thrombocytopenic purpura (ITP) is a bleeding condition in which the blood doesn't clot as it should. This is due to a low number of blood cell fragments called platelets.
Aphasia is a condition that is the result of damage to portions of the brain. It can be caused by stroke, head injury, brain tumor, or infection. There are two types of aphasia, fluent and non-fluent. Some patients may fully recover from aphasia over time, while others may not.
Coma is the inability to waken or react to the surrounding environment. The Glasgow Coma Scale is frequently used to measure the depth of coma. Causes of coma include trauma, bleeding, edema, lack of oxygen, poisoning, or hypoglycemia. Prognosis for a patient in a coma depends on the cause of the coma.
Shaken Baby Syndrome (Abusive Head Trauma)
Shaken baby syndrome, or abusive head trauma, is the condition that describes the symptoms and signs that result from the violent shaking of an infant. These symptoms and signs include: bruising, vomiting, poor feeding, seizures, head trauma, and hemorrhages of the retina. Shaken baby sundrome treatment involves removing the infant from the household where the abuse occurred and providing supportive care for the child's injuries.
Stroke is the third leading killer in the United States. Some of the warning signs of stroke include sudden confusion, trouble seeing with one or both eyes, dizziness, loss of balance, and more. Stroke prevention and reatable risk factors for stroke include lowering high blood pressure, quit smoking, heart disease, diabetes control and prevention.
