The Effects Of Lyme Disease On The Nervous System
Neurological disease Any disease or abnormality that affects the functioning of the human nervous system Everything that humans experience, consider, and affect, including the body’s reactions, is not fully learned. Depends on the functioning of the nervous system. The skeleton and muscles support and transport the body. and the digestive system, heart, and lungs provide nutrients. But the nervous system contains the epitome of humanity: the mind, and it controls all perception, thought, and action. Disturbances or malfunctions of the nervous system cause changes throughout the body. Although many brain diseases cause abnormalities in thought or mood, But this article will only discuss diseases of the nervous system that have natural causes. To discuss mental disorders
The first part of this article describes the neurological examination, including the medical history. Physical examination of the patient Tests and diagnostic procedures that can be used to provide doctors with information about possible neurological disorders. Next, we will explain the principles used to limit disease within the nervous system. The third part of this article provides an overview of the pathological process. Finally, diseases of the nervous system will be discussed. It uses a general classification based on the primary or important location of the disease.
An old proverb in medicine goes, “Listen to the patient; He is telling you the diagnosis,” especially in neurology. Patient descriptions of symptoms are a valuable tool in helping doctors learn about the nature and location of potential neurologic disease. While taking the patient’s medical history The neurologist records the patient’s level of awareness. memory loss Posture and gait Behavior and expressions, words, and some aspects of personality Neurologists also note symptoms such as pain, headaches, loss of sensation, weakness, incoordination, loss of certain muscle groups. and abnormal movement
The ability to observe and respond to one’s environment is not an on-off phenomenon. But it is a continuous phenomenon. from full alertness A person can go from drowsy to dazed. A condition in which awareness is greatly reduced. And the best motor response to a stimulus is a moan or other acoustic response. (but not verbal) Deep unconsciousness passes into light coma. where strong stimulation produces only a clumsy mechanical response. to a deep coma in which there is only reflex movement or no response at all Such depression occurs when the function of the brainstem or cerebral cortex is impaired. Brainstem abnormalities can cause coma if the brainstem is compressed by other parts. of brain swelling due to disease or if it is a local disease such as encephalitis Stroke or a concussion Diseases of the cerebral cortex that cause coma include poisoning from sedatives. Lack of glucose or oxygen in the blood brain hemorrhage and rare infiltrative disorders where the descent from consciousness occurs over weeks or months. brief loss of consciousness which the patient may not know Occurs in many forms of epilepsy. narcolepsy Recurrent episodes of hypoglycemia and the amount of blood that goes to the brain decreases especially the brainstem
How Huntington’s Disease Affects Different Neurons
When the pressure inside the skull increases Pain-sensitive structures in and around The brain is distorted. and causes pain in areas that are not in position But they can often be identified at the front or back of the head. It’s called traction headache. Traction headaches can be caused by swelling of the brain, infection, bleeding, tumor, stress, or blockage of cerebrospinal fluid flow. In addition, pain may be felt in the head area even though the abnormality causing the pain is elsewhere. For example, facial pain sometimes occurs when there is not enough blood flowing to the heart. Local diseases of skull structures such as the jaw joints The paranasal sinuses and teeth, middle ear, and skull bones can also cause pain.
Tension headaches are caused by excessive, prolonged contraction of the muscles running from the front to the back of the skull. These headaches are often caused by stress. It is often described as a constant pain of pressing or pulling. which often has tremors Migraine headaches can occur at the same time as tension headaches. characterized by a throbbing pain Symptoms include scalp tenderness, nausea, vomiting, and sensitivity to sound and light.
Poor concentration caused by obsession, fatigue, or depression is the most common cause of memory loss. But a progressive brain disease Vitamin deficiency, epilepsy and dementia (loss of intellectual power) is also a cause. When the duration of memory loss is clearly determined The main causes are head injury, seizures, poisoning (such as alcohol) and insufficient blood supply to the brain. Impaired understanding, reasoning, and logical thinking And the ability to plan ahead can also be a symptom of neurological disease.
Patients with aphasia may know exactly what they want to say. but cannot express his thoughts in words If they are unable to understand (and often write) language, they may not be able to understand the meaning of spoken or written language, so normal speech sounds like a foreign language. Stroke is the most common cause of aphasia. But focal encephalopathy may be responsible.

Similar language and speech comprehension problems are apraxia and agnosia. Apraxia is the inability to perform useful or skilled actions. Apraxic patients may be able to name objects such as a comb or keys. But they may not know how to use it. Agnosia is the failure to understand the importance of non-verbal stimuli. Patients with unknown causes may be unable to recognize the origin of sounds from musical instruments.
Dysarthria or difficulty with articulation It is usually caused by abnormalities in the nerves and muscles in and around the mouth or in their connections. Problems producing speech, called dysphonia, usually indicates a problem affecting the larynx or the nerves and muscles of that structure. This is because cranial nerves supplying these areas originate in the brainstem. Neurological diseases in this region can also be the cause. Peripheral neuropathy refers to any condition. that affects nerves outside your brain or spinal cord This can happen for many reasons. From wounds to infections to inherited conditions. There are also many possible symptoms. There are many possible causes, forms, or symptoms of this condition that can be treated. But it can vary greatly from person to person.
Peripheral neuropathy can affect any nerve in the body. It can interfere with the control of the body’s automatic processes. The same is true of touch and muscle control.
Peripheral neuropathy is the term used to describe nerve diseases that affect specific parts of your nervous system. Many different conditions can cause peripheral neuropathy. This means that a wide range of symptoms can occur as well. Peripheral neuropathy can affect different parts of the body, depending on how and why it happened.

The word “peripheral” comes from the Greek word for “around.” “Peripheral” in this context means outside or away from the “central” nervous system. The term neuropathy combines two words that trace back their origins. From ancient Greek:
Your nervous system has two parts: the central nervous system and the peripheral nervous system. Your brain and spinal cord are the two components that make up your central nervous system. The peripheral nervous system is made up of other nerves. all in your body It also includes nerves that travel from the spinal cord and brain to the face and other parts of the body.
Peripheral neuropathy can refer to any condition. that affects your peripheral nerves Healthcare providers often use the term The terms “neuropathy” and “peripheral neuropathy” (meaning “disease of multiple nerves”) are interchanged with “peripheral neuropathy.” Peripheral nerves are the furthest from the central nervous system. And these symptoms often appear in the earliest and most severe stages.

Parkinson’s Disease Outside The Brain: Targeting The Autonomic Nervous System
Peripheral neuropathy can happen to anyone. regardless of age, gender, race or ethnicity personal situation medical history, etc. However, some people are at higher risk for specific types of peripheral neuropathy. (See below on causes and symptoms for more information on this).
Peripheral neuropathy is also very common in some age-related diseases. That means your risk of developing peripheral neuropathy increases as you get older.
Peripheral neuropathy is common. This is partly because the term refers to a wide range of conditions: approximately 2.4% of people worldwide have some form of peripheral neuropathy. Among those 45 and older, that percentage rose to between 5% and 7%.
To understand how peripheral neuropathy affects your body Knowing a little about this disease will help you understand it.
