There are various nervous system conditions that need to be treated clinically by a doctor or other healthcare provider. Depending on the type of condition and the particular location, the symptoms of neurological disorders can vary significantly. Sometimes you may feel emotional problems while other times you may only experience physical symptoms. 

Below are some common neurological conditions and their symptoms to watch for. 

1. Alzheimer's Disease

The majority of dementia cases are caused by Alzheimer's disease. About 5.2 million Americans over the age of 65, as well as tens of thousands of people under the age of 65, have early-onset Alzheimer's. Nearly two-thirds of Americans with Alzheimer's disease are women. Diagnosis for Alzheimer's disease can be made with up to 95% accuracy by ruling out other conditions that present with similar symptoms.

Compared to other types of dementia, the motor function of people with Alzheimer's disease is usually not affected until the late stage. The most common early symptoms of Alzheimer's disease include memory loss that affects daily life, problems with language, problems with abstract thinking, and mood or behavioral changes. Later, patients may lose the ability to recognize people, even well-known ones. For this reason, this condition requires the supervision of an experienced neurologist. 

2. Bell's palsy

Bell’s palsy is a neurological disorder that causes facial muscular paralysis or weakening. Over the course of 48 hours, it gets worse suddenly. Anyone can get Bell's palsy, no matter their age or gender. Pregnant women and those with diabetes, flu, cold, or any upper respiratory condition are more likely to acquire it. Both men and women can have Bell's palsy. Bell’s palsy may cause rapid onset of weakness or total paralysis on one side of your face and facial pain.

Bell's palsy isn’t thought to be permanent. But in rare cases, it might become a permanent issue. While there is no cure for Bell’s palsy, the recovery usually begins 2 weeks to 6 months after the onset of the symptoms.

3. Epilepsy

Epilepsy is a neurological illness that affects the brain and increases a person's risk of recurring seizures. All ages, races, and cultural backgrounds may be affected by this condition. There are 2.2 million epilepsy patients in the United States. Seizures can be triggered by anything that breaks the normal connections between the brain's nerve cells. A high temperature, low blood sugar, high blood sugar, and alcohol or drug withdrawal are common examples. Everyone may experience one or more seizures in these conditions. But people are thought to have epilepsy if they experience two or more seizures. 

Epilepsia may be caused by a variety of factors, such as an imbalance of neurotransmitters, tumors, strokes, brain damage from disease or trauma, or a combination of these. However, epilepsy has no known cause in most cases.

4. Parkinson's Disease

Parkinson's disease affects more than one million Americans. This degenerative disease, which mainly affects adults over 65, gradually worsens motor skills, leaving people with a slow and awkward gait, rigid limbs, tremors, shuffling, and poor balance. No one knows what causes Parkinson's disease. Most cases develop spontaneously, however, some are inherited. 

What is known about Parkinson’s disease is that the "substantia nigra," a region of the brain, experiences the death of brain cells. These are the cells that produce the neurotransmitter dopamine, which aids in controlling muscular activity. 

5. Multiple Sclerosis

Multiple sclerosis (MS) is a long-lasting (chronic) disease of the central nervous system. It is believed to be an autoimmune illness, in which the body unintentionally attacks itself. MS is an unexpected illness that has various effects on the human body. Some people experience only mild symptoms. But because of severe damage, when the brain and other parts of the body can no longer communicate, people may lose their ability to see properly, write, talk, or even move.

Mild to severe problems caused by MS might include everything from fatigue to inability to move. Cognitive decline, balance issues, and bowel or bladder control are among more issues. The stress caused by managing a chronic disease can also lead to depression.
