Medications that affect the central nervous system are among the most important medical tools to confront neurological and psychological disorders, as World Health Organization reports indicate that neurological diseases have become the main cause of illness and physical disability, and therefore the Rafah Center at Al Mousa Specialist Hospital is at the forefront of the most important medical centers that provide the necessary care, so follow with us the following very carefully; 

What is the central nervous system?

The central nervous system is the basic part of the nervous system in the human body, and it consists of the brain and spinal cord. Its main function lies in receiving information from the body and the environment, then processing it, and then sending commands to the rest of the body’s organs through the peripheral nervous system, but it can be said that:

• The brain is responsible for thinking, memory, sensory control, and feelings.
• The spinal cord transmits nerve signals between the brain and the rest of the body, and is also involved in some rapid responses.

What are the most important functions of the central nervous system?

The central nervous system is the main control unit in the human body.

• Sensory information processing: It receives signals from the five senses, then translates them into images, sounds, or feelings that can be perceived.
• Coordinating and organizing movements: It issues orders to the muscles to perform voluntary movements, such as walking, and involuntary movements, such as breathing.
• Thinking, memory, and learning: The brain is the center of higher mental processes such as concentration, analysis, planning, and memorizing information and recalling it when needed.
• Controlling emotions and behavior: It participates in the formation of emotions such as joy, fear, and anger, and directly affects behavior and responses.
• Regulating vital functions: It controls involuntary processes such as heartbeat, blood pressure, breathing, and digestion through specialized centers in the brain.
• Formation of rapid responses: Through the spinal cord, the body can respond quickly to stimuli, such as withdrawing the hand if it touches a hot object to protect it from danger.

What are the medications that affect the central nervous system?

Drugs affecting the central nervous system (CNS) are a wide group of drugs that affect the functions of the brain and spinal cord, leading to changes in cognition, mood, consciousness, or behavior. These drugs are divided into main categories based on their pharmacological effect. Below we provide you with an overview of the most important categories.

1. Sedatives and Hypnotics:

They are used to reduce nervous activity, promote relaxation, or induce sleep, including:

• Benzodiazepines such as diazepam, lorazepam: used to treat anxiety, insomnia, and epileptic seizures.
• Barbiturates such as phenobarbital: These are used in anesthesia or to treat epilepsy, but are less common now due to their side effects.
• Non-benzodiazepines such as zolpidem: used to treat insomnia.

2. Antidepressants:

It is used to treat depression and other mood disorders, by adjusting the levels of neurotransmitters, including:

• Selective serotonin reuptake inhibitors (SSRIs): such as fluoxetine and sertraline.
• Tricyclic antidepressants (TCAs): such as amitriptyline.
• Monoamine oxidase inhibitors (MAOIs): such as phenelzine.

3. Antipsychotics:

It is used to treat schizophrenia, bipolar disorder, and hallucinations by affecting dopamine and serotonin, including:

• Typical first generation: such as haloperidol.
• Second generation atypical: such as risperidone and olanzapine.

4. Stimulants:

It increases the activity of the central nervous system, and is used to treat attention deficit hyperactivity disorder (ADHD) or narcolepsy, including:

• Methylphenidate: such as Ritalin.
• Amphetamines: such as Adderall.

5. Anticonvulsants:

It is used to stabilize electrical activity in the brain to treat epilepsy or bipolar disorders, including:

• Carbamazepine.
• Sodium valproate.
• Lamotrigine.

6. Opioid pain relievers (Opioid Analgesics):

It is used to relieve severe pain by affecting opioid receptors in the brain, including:

• morphine.
• Oxycodone.
• Fentanyl.

7. Anesthetics:

It is used to induce loss of consciousness, or local anesthesia during surgical operations, including:

• General: such as propofol and sevoflurane.
• Topical: such as lidocaine.

8. Anti-anxiety medications (Anxiolytics):

It is used to relieve anxiety and tension, including:

• Benzodiazepines: such as alprazolam.
• Buspirone.

9. Medications to treat Parkinson’s disease:

It is used to modify dopamine levels, or improve motor control, including:

• Levodopa/carbidopa.
• Amantadine.

10. Non-drug hypnotics and recreational drugs:

Some non-medicinal substances affect the central nervous system, including:

• Alcohol.
• Nicotine and drugs.

Based on the multiplicity and types of medications, the doctors at the Rafah Psychiatry Center at Al Mousa Specialist Hospital confirm that the choice of medication depends on the accurate diagnosis, as medications that affect the central nervous system can be used either to increase the activity of the neural pathways, or to reduce nervous hyperactivity, so do not rush to buy the medication without consulting the medical team at Al Mousa Specialist Hospital;

How do neurons communicate?

Communication between nerve cells is the basis of the functioning of the central nervous system, as it is what allows the transmission of information within the brain and between the brain and the rest of the body, as there are sequential stages to this process, which are:

1. Transmission of the signal inside the cell: The process begins with the occurrence of a small electrical charge called the action potential, which is transmitted along the length of the nerve cell from the cell body to its end.
2. Signal transmission between cells: When the signal reaches the end of the cell, chemical substances known as neurotransmitters are secreted into a small space between two cells called a synapse. These transmitters then bind to receptors on the next cell, causing that cell to be stimulated or inhibited depending on the type of neurotransmitter.
3. Signal termination: After the neurotransmitter has performed its function, it is quickly removed, either by breaking it down with special enzymes, or returning it back to the first neuron;
4. Neuroplasticity: Neurons have the ability to strengthen or weaken these connections over time, which is known as neuroplasticity, which is the basis for learning and memory processes.

How do neurological diseases affect the central nervous system?

Neurological diseases are among the most dangerous disorders to human health.

• Weak nerve signals: Some diseases, such as multiple sclerosis, attack the insulating covering of nerves, which slows or stops the transmission of signals between the brain and the rest of the body, causing the patient to exhibit weak movement or difficulty balancing.
• Nerve cell loss: Diseases such as Alzheimer's and Parkinson's lead to the gradual death of nerve cells, which causes memory problems, movement disorders, and a decline in cognitive abilities.
• Imbalance in neurotransmitters: Some disorders, such as depression and epilepsy, are linked to an imbalance in the chemicals responsible for transmitting signals between nerve cells, which affects mood or causes abnormal electrical seizures.
• Tumors and injuries: They can cause pressure on specific areas of the brain or spinal cord, thus hindering their function, leading to symptoms such as loss of sensation or difficulty speaking.

Here comes the role of medical care and the use of some medications that affect the central nervous system, which may help compensate for this imbalance by activating some neural pathways or inhibiting excessive activity. Symptoms can only be controlled and quality of life improved by seeking help from the medical team of Al Mousa Specialist Hospital, which prescribes the appropriate medication for your condition.

Frequently asked questions about medications that affect the central nervous system 

What are nervous system stimulant medications?

These are medications that increase the activity of the central nervous system, such as caffeine, amphetamine, and nicotine, and help raise the level of concentration and attention and reduce the feeling of fatigue.

How do tranquilizers affect the nervous system?

Tranquilizers slow down the activity of the central nervous system, by enhancing the action of the neurotransmitter GABA, which causes relaxation and reduces anxiety, and may help with sleep.

What causes disorders in the central nervous system?

Disorders may result from genetic factors, direct injuries to the brain or spinal cord, infections and tumors, or the result of chronic diseases such as multiple sclerosis and Alzheimer's, in addition to defects in neurotransmitters.
