One of the biggest risks of illicit drug use or even prescription drugs, when they are misused, is overdosing. A drug overdose can cause long-term damage and may result in toxic brain injury. If you or someone you love has suffered from a drug overdose, it’s helpful to understand this condition.
What is Toxic Brain Injury?
Toxic brain injury occurs with cerebral blood flow stops going to the brain tissue, which is also known as anoxic encephalopathy. It can also be referred to as hypoxic-ischemic brain injury. When it happens because of a drug overdose, the term toxic brain injury is used. Anoxic brain injury occurs when the person stops breathing while hypoxic injury happens when the breathing slows down to a dangerous level.
This condition can happen from poisoning, cardiac arrest, or vascular injury, but it also occurs with drug overdoses. Many people die without ever regaining consciousness. Others will suffer various levels of damage from the loss of blood flow. When a person overdoses, their heart rate, and breathing may slow to dangerous levels even if they don’t stop breathing completely. If the brain doesn’t get enough oxygen, it can lead to damage.
Brain injury may be identified soon after the overdose occurs. Testing may indicate a lack of oxygen, and CT scans of the brain are generally performed to determine damage. The initial evaluation may return normal, but subsequent imaging may indicate anoxic injury. The doctor may order an MRI to help with diagnosis as well¹.
A doctor may order an electroencephalogram (EEG), which measures the brain’s electrical activity. They may use evoked potentials testing to determine if the brain has a response to sensations, such as touch².
Toxic Brain Injury Treatment
The first step in toxic brain injury treatment is stabilizing the patient. The next step is diagnosis. Other scenarios may mimic the signs of brain injury, such as sepsis, sedation medication, or even drug overdose and alcohol intoxication. Initially, the patient may be in a comatose state. In time, they may show recovery or stay in a vegetative state even to the point of brain death. A vegetative state may still maintain a sleep-wake cycle even though there is no self-awareness¹.
At the time of the overdose, emergency personnel will work to restore oxygen flow to the brain. They may use Naloxone to counter the overdose and perform CPR or give the person oxygen until they can breathe independently.
What are the Signs of Brain Damage from Drugs?
The amount of damage done to the brain will depend on how long the person had limited or no oxygen going to the brain. The more severe the condition, the more long-term effects the person may experience. Brain cells begin to die in just five minutes of low oxygen. Signs that indicate the person is suffering from hypoxia include:
- Shallow breathing, rapid breathing, or not breathing at all
- Person appears disoriented
- They slur their words
- Skin and lips develop a bluish or grayish tint
- Pupils are dilated
- Person experiences seizures or convulsions
- No response when spoken to²
If a person shows these signs after taking drugs, you need to call for help immediately.
What are the Effects and Treatment of Drug Overdose on the Brain?
The person who experiences symptoms of brain damage from a drug overdose may exhibit the following:
- Memory loss or other cognitive impairment
- Inability to focus
- Changes in personality
- Poor judgment
- Speech issues
- Difficulty swallowing
- Issues with balance, walking, and coordination
- Muscle spasms or full body muscle contractions
- Problems with vision
While brain death can occur after ten minutes without oxygen, damage can begin in just a few minutes².
After a diagnosis and immediate care has been made, a doctor may recommend physical, occupational, and speech therapy to help with recovery. These therapies cannot cure dead brain cells, but they can help the person learn new ways of functioning and develop new pathways in the brain. If the hypoxia was severe, the damage may be permanent.
What Causes a Drug Overdose
The best way to prevent brain damage from a drug overdose is to prevent the overdose. If you or a loved one is abusing drugs or alcohol, you need to seek treatment. A drug overdose can happen quickly, especially if you mix substances. It’s essential to recognize and avoid the risks before an overdose occurs. Mixing drugs with alcohol makes you more susceptible to an overdose because one substance can mask the symptoms of another substance.
For instance, an alcohol overdose happens when a person has too much alcohol in the bloodstream that basic systems of the body begin to shut down, such as heart rate and breathing. If the person is also taking opioids or other drugs with sedative effects, it can increase the risk of alcohol overdose. The person may become confused, start vomiting, have trouble breathing and a slow heart rate, and develop clammy skin. Their body temperature may drop dangerously low³.
A person is at an increased risk of an overdose if they consume too much of the substance too quickly. This situation is often seen with binge drinking.
How to Prevent a Drug Overdose
Preventing a drug overdose begins with being aware of which substances you are consuming and how much. Avoid mixing substances and drink alcohol more slowly. It also helps to drink after you have eaten because the food helps to absorb the alcohol.
If you have trouble stopping once you start drinking or using drugs, it’s better if you don’t start. You may have a dependency or even an addiction to the substance. In this case, you need to seek addiction treatment.
