Head Injuries

Chances are you’ve bumped your head before. Often, the injury is minor because your skull is hard and it protects your brain. But other head injuries can be more severe, such as a skull fracture, concussion, or traumatic brain injury.

Head injuries can be open or closed. A closed injury does not break through the skull. With an open, or penetrating, injury, an object pierces the skull and enters the brain. Closed injuries are not always less severe than open injuries.

Some common causes of head injuries are falls, motor vehicle accidents, violence, and sports injuries.

It is important to know the warning signs of a moderate or severe head injury. Get help immediately if the injured person has:

• A headache that gets worse or does not go away
• Repeated vomiting or nausea
• Convulsions or seizures
• An inability to wake up
• Dilated (enlarged) pupil in one or both eyes
• Slurred speech
• Weakness or numbness in the arms or legs
• Loss of coordination
• Increased confusion, restlessness, or agitation

Doctors use a neurologic exam and imaging tests to make a diagnosis. Treatment depends on the type of injury and how severe it is.

Health Fraud

Health fraud scams involve selling medicines, supplements, devices, foods, or cosmetics that have not been proven effective. At best, these scams don’t work. At worst, they’re dangerous. They also waste money and might keep you from getting the treatment you really need.

Some of the possible dangers of scam products are that they could:

• Be contaminated from being made in unclean facilities or without proper quality control
• Contain harmful ingredients that are not listed on the label
• Trigger a harmful interaction with medicines you are taking
• Cause serious, even life-threatening, injuries

Health fraud scams can be found everywhere, promising help for many common health issues, including weight loss, memory loss, sexual performance, and joint pain. They target people with serious conditions such as cancer, diabetes, heart disease, HIV, and Alzheimer’s disease.

Just remember – if it sounds too good to be true, it’s probably a scam. Some red flags to watch for are product claims that:

• Have personal testimonials by “real” people or “doctors” played by actors claiming amazing results.
• Say that the product can treat or cure a wide range of unrelated diseases. No one product can treat or cure many different illnesses.
• Mention conspiracy theories like “This is the cure our government and Big Pharma don’t want you to know about.”
• Include phrases such as:
  • Ancient remedy
  • Miracle cure
  • No-risk money back guarantee
  • Natural cure
  • Quick fix
  • Secret ingredient
  • Scientific breakthrough
• Use scientific-sounding terms that don’t make sense for the products, such as “molecule multiplicity.”
• Refer to prestigious prizes, for example “Nobel Prize winning technology.”

Before taking an unproven or little-known product, talk to your health care provider, especially if you are taking any prescription medicines.
