Recovering from a Concussion




A concussion is a type of traumatic brain injury, and it can occur anytime a person hits their head on something. It’s one of the most common injuries in a car accident. According to an article in Medical News Today, most people recover from a concussion in about a month.

What is a Concussion?

A person can get a concussion when the head is hit with direct force, which causes damage to the brain. In a car accident, it most often happens if the person’s head hits the dashboard or other object in the vehicle. Concussions range from mild to severe, but even mild ones may require medical attention.

Sometimes, there are no symptoms with a concussion, and the person isn’t even aware they’ve had one. In other cases, the symptoms can last for several weeks. According to information from the CDC (Centers for Disease Control and Prevention), 2.87 million ER visits, hospital stays and deaths were attributed to traumatic brain injuries in 2014.

Symptoms of a concussion include the following:

  • Headaches
  • Nausea
  • Fatigue
  • Issues with vision
  • Problems with balance
  • Changes in mood
  • Difficulty with concentration and thinking
  • More sensitivity to light and sounds
  • Problems sleeping

Sometimes concussion symptoms don’t show up right away. Some may be noticeable after the injury while others may take days or even weeks to begin.

Recovery Process

In the first two to three days after a concussion, the person should spend most of their time resting. Even if they feel normal, they should cut back on activities. Ideally, they won’t be alone for the first 48 hours. After the initial period, they should return to normal activities slowly.

A doctor will let them know when they are ready to drive, go back to work, resume exercise or physical activities and drink alcohol.

One factor that will determine how long it will take to recover from a concussion is how severe it was. A person with a history of concussions may also take longer to heal or if they have other pre-existing neurological issues. People who are older will generally take longer to heal of any medical issue, including a concussion.

Rest is the best medicine for a concussion. Eating healthy and not doing strenuous activities will also help. It is important to seek medical treatment after a head injury, no matter how minor it may seem. You shouldn’t treat it on your own because you don’t know how much damage there might be.

If a person takes longer than six weeks to recover, they may have what is known as post-concussion syndrome. It’s important to be careful and not get another concussion while this one is healing. Traumatic brain injury is a serious condition and should never be taken lightly. Even though concussions are common, they shouldn’t be ignored. Getting medical treatment right away is the best option to determine how serious the TBI is and if there are any long-term effects. With the right treatment plan, it’s likely that the person will make a full recover from a concussion.

New Report Shows Automated Driving Systems Not Equal to Human Drivers




Automated systems have progressed quickly in the automotive industry. Vehicles can park and even drive without the assistance of drivers in some cases. However, a new study by AAA indicates that these systems still aren’t as reliable and safe as human drivers.

Flawed Systems

According to the report by AAA, the current automation systems are limited. They still require drivers to pay attention and not rely on them completely as they drive to prevent accidents. Researchers conducted tests of vehicle automation systems, including Ford CoPilot 360 and GM Super Cruise. These systems help the driver by performing steering, braking and acceleration at least partially without human intervention.

Research indicates that the systems aren’t always consistent in their performance. Some vehicles failed to stay within the designated lane and would occasionally steer too close to traffic coming from the other direction. Many of these systems have lane monitoring to keep vehicles in the correct lane.

The systems also come with automatic braking for emergencies or stopped traffic. AAA found that sometimes the vehicles may brake abruptly, not giving the vehicle behind them enough time to stop, resulting in a rear-end collision. These systems are also supposed to recognize obstacles to avoid accidents. However, some tests showed that they didn’t adjust direction to avoid a disabled vehicle that was in the roadway.

The manufacturers don’t claim perfection when it comes to the systems. In fact, they often include the shortcomings of the vehicle in the owners’ manuals. However, drivers often expect perfect performance when they drive. They rely solely on the automated systems rather than paying attention to the situation.

Based partly on the results of the study, AAA is asking manufacturers to improve these systems, often known as Level 2 systems, before they add them to new models. This isn’t the first test done of automated systems. The results are similar to other studies done by the Insurance Institute for Highway Safety (IIHS). Consumer Reports has also seen similar results in evaluations of systems.

The Testing

AAA used five vehicles for testing:

  • 2019 Ford Edge
  • 2019 BMW X7
  • 2019 Cadillac XT6
  • 2020 Subaru Outback
  • 2020 Kia Telluride

All models feature active driving assistance. All but the Cadillac and Ford models were tested on the AAA closed test track. Those two models had limitations on location and speed. All five models were tested on a round trip between Los Angeles and San Francisco, which totaled 800 miles. They were driven on interstates as well as local highways.

All five models have problems with being able to stay in the correct lane. They fared well on the closed track, except for some left bias, which would put them closer to oncoming traffic. All five had issues on curving roads and hills.

While AAA admitted that some models worked better in various situations than others, none could be completely relied upon. The researchers recommend that drivers continue to pay attention and use the systems as assistance, but not to rely on them to do the job alone.

Eye Test May Detect Brain Injury




An eye test may possibly detect brain injury according to one study. This test uses a handheld device to look for changes in the size of pupils and is non-invasive.

The small study indicated that the quantitative pupillometry was able to detect indications of brain injury in high school football players who had shown no other signs of a concussion. The device looks for neurological effects from head impacts that are measurable. The players hadn’t been diagnosed with a brain injury.

The impacts which have no symptoms to accompany them may still be severe and can result in subtle changes in the brain. Doctors recommend that a player receive an evaluation for head injury or brain trauma even if they show no signs at all after a severe impact.

Normally, these head impact injuries are only able to be detected and diagnosed by using advance imaging as well as biomarkers. These methods are invasive as well as costly. They also take time. QP could provide a non-invasive way to assess the damage of these impacts. QP has become common in use to detect pupil changes for other reasons over the use of a penlight, which can be subjective. The device measures pupil size as well as reactivity. It takes only two minutes to use on a patient.

Traumatic Brain Injury

While the study involved 18 high school football players, athletes aren’t the only ones who could benefit from this new information. TBIs can happen in any situation where a person suffers a severe impact to the head. For instance, one of the most common injuries from a car crash is impact to the head.

Often, the person may not notice any issues right away. They may say they feel fine. They could be in shock or genuinely feel fine at the time. However, a quick test for potential brain trauma could provide information which would tell them of brain injury at the earliest point possible.

Many times, a person may not exhibit symptoms from a TBI for days, weeks or even months after the accident. Even if they do show signs, they may not associate them with the trauma. They may suffer from memory loss, fatigue, changes in personality or behavior.

Concussions are commonly labeled as mild, moderate or severe. Signs of one include the following:

  • Confusion
  • Double vision
  • Headache
  • Drowsiness
  • Blurred vision
  • Dizziness
  • Nausea or vomiting
  • Problems with balance
  • Sensitive to light or sounds

To treat a concussion, the doctor will usually prescribe rest and OTC pain medication. They will usually restrict activities for a period of time. For severe concussions, surgery may be necessary.

Because of the seriousness of brain injury, it’s important to get checked out any time you suffer from a hit to the head. Even if you feel fine, you could have suffered damage to the brain. It takes time for the brain to heal, but it’s also critical that you avoid risk of another head injury during that time. Multiple traumas increase the risk of long-term damage.

Vehicles Improving on Pedestrian Detection




Vehicle manufacturers are improving the technology that detects pedestrians, which will hopefully reduce the number of pedestrians killed each year. In fact, six mid-size cars received top marks from the IIHS while seven more came in second with a score of advanced. In total, 19 vehicle models in this category were reviewed, and only two received no credit.

Some Models Rise to the Top

Consumer Reports scores vehicles based on safety. More points are awarded if the technology for detecting pedestrians is included as standard equipment on vehicles. Experts say these systems could reduce pedestrian fatalities by thousands. Reports show that more than 100 pedestrians die each day in roadway accidents.

Statistics show that the number of pedestrians that died on the roadways in the US in 2018 were up from the previous years. The totals were higher than in the past three decades. This is concerning not only for the loss of lives but because more technology is in place to help drivers avoid crashes.

According to the National Highway Traffic Safety Administration (NHTSA), there was a 3.4 percent increase in pedestrian fatalities in 2018 from 2017 with a total of 6,283. This is in stark contrast to the decline of total fatalities in highway accidents, which went down by 2.4 percent. This continues a trend with over 50 percent more people being killed as pedestrians that what occurred in 2009.

Testing done by IIHs for pedestrian safety included three different situations. In the first, the person is walking in front of a vehicle which is traveling at two different speeds. In one, the car is at 12 mph while in the second one it is traveling at 25 mph. The second situation being tested is a child that is running between cars which are parked. The third involves an adult walking along the shoulder.

All tests are conducted during the day with dry conditions. The cars being tested are expected to recognize the presence of a person and begin slowing down. The cars that scored the highest include the following:

  • Volvo S60
  • Subaru Outback
  • Audi A4
  • Nissan Maxima
  • BMW 3 Series
  • Mercedes-Benz C-Class

Based on results, these vehicles would have avoiding hitting the pedestrian in all tests.

The three models that failed all tests were the Kia Optima, Ford Fusion and Hyundai Sonata.

Pedestrian Detection Technology Helps

Vehicles that include pedestrian detection are equipped with cameras and sensors as well as radar. The systems are designed to recognize a pedestrian even if the driver is unaware of their presence. The vehicle is supposed to be able to apply the brakes even if the driver doesn’t.

These tests show that advanced technology can help prevent pedestrian injuries and deaths. Experts say that the equipment should be available for all buyers rather than being limited to luxury models. When a pedestrian is struck by a vehicle, the risk of serious injury or death is much higher than if the person were in another vehicle. Because they are less visible, it’s often difficult for drivers to see the person walking in enough time to slow down before a collision takes place.
