A stroke, also called cerebrovascular accident (CVA), cerebrovascular insult(CVI), or brain attack, occurs when a part of the brain is deprived of blood flow. When the brain cells are deprived of oxygen they begin to die. When brain cells die, the functions controlled by that part of the brain also stops, which results in different types of disabilities among stroke survivors.

There are two types of strokes

Hemorrhagic
Ischemic stroke
The first is caused when a brain aneurysm or a weak blood vessel bursts. Most of the time, this type of stroke leads to death. The second one happens when a clot blocks the flow of blood to the brain. Patients suffering from stroke suffer from various side-effects, the most common ones being paralysis or loss of feeling in a certain part of the body, problem in understanding or talking and loss of vision in one side. The side-effects start showing up regularly after a person has had a stroke.

In certain conditions, blood flow to a certain part of the brain stops for only some time and hence the body suffers stroke like symptoms which only last a couple of hours before disappearing. This is known as a transient ischemic attack (TIA). Unfortunately, the effects of a stroke can be debilitating and also permanent. Hence its important to know the symptoms of a stroke and rush the patient to a doctor as soon as possible. Sometimes early treatment can save a lot of damage.

The primary symptoms of stroke are as follows:

Confusion and problems with talking and comprehension
Headache along with alteration of consciousness or vomiting
Numbness of the face, arms or legs, especially on one side of the body
Issue with seeing, in one or both eyes
Inability to walk with stability, including disrupted coordination
Problems with the bladder and bowel control
Acute depression
Body temperature fluctuates, and pain worsens with movement
Paralysis on one side of the body along with fatigue
Problem in expressing or controlling emotions
Risk Factors:

Hypertension
Diabetes
Increased Cholesterol
Smoking
Obesity
Sedentary Lifestyle
Diagnosis of stroke

Several tests are carried out to determine the type of stroke acquired. They are:

Physical examination, which involves observing the patient's overall condition.
Blood tests
CT scans
MRI scans
Cerebral angiogram
Echocardiograms
Stroke is a fatal brain disease and can cause permanent damage to your system so its best to check with your doctor to know how you can prevent it.

Brain Stroke - Factors That Can Lead To It!

Dementia cannot be singularly regarded as a specific disease, but rather indicates a group of symptoms associated with your memory, cognitive thinking, and social abilities, up to the point where daily functioning gets affected. In most cases, dementia steadily worsens over time (progressive dementias). Dementia is not to be confused with memory loss alone; because it is natural with old people to experience memory loss, but that does not necessarily mean they have dementia. If the reason is dementia, then you may require medical treatment.

Causes

Dementias are generally caused either by damage to or changes in the nerve cells operating in the brain. The causes can be grouped differently based on the type of dementia experienced and the part of the brain affected. While some causes can be reversed with effective treatment, others, unfortunately, cannot.

The most common causes of dementia which cannot be reversed include:

1. Alzheimer's disease
2. Vascular dementia
3. Parkinson's disease
4. Frontotemporal dementia
5. Dementia with Lewy (dementia which is neurodegenerative and progressive in nature) bodies
6. Severe head injuries

Other irreversible causes which are relatively rarer than usual include:

1. Huntington's disease (breakage of the brain's nerve cells)
2. Creutzfeldt-jakob disease (irreversible and fatal brain disease)
3. Multiple sclerosis or amyotrophic lateral sclerosis
4. Infections like syphilis
5. Leukoencephalopathies (diseases affecting the brain's'white' areas)
6. Brain injuries
7. Multiple system atrophy

Causes of dementia which can be treated include:

1. Hypothyroidism
2. Heavy metal poisoning
3. Certain brain tumors
4. Chronic alcoholism
5. Hiv/aids
6. Vitamin b12 deficiency
7. Medicinal side effects or abnormal drug reactions
8. Normal pressure hydrocephalus
9. Certain cases of encephalitis

Symptoms

Symptoms of dementia include:

1. Memory loss
2. Difficulty finding the right words
3. Difficulty exercising judgments, especially during emergencies
4. Inability to recall particular events or to recognize people and places
5. Depression or other mood disorders, in addition to symptoms like uncontrolled aggression or constant agitation.

Causes and Symptoms of Dementia

What is Parkinson s disease?
Parkinson s disease is a progressive and degenerative disorder of the Central Nervous System that mostly affects older people. It is a chronic disease and the symptoms develop over a period of time. The characteristic symptoms of Parkinson s are rigidity, shaking, bradykinesia (slowness in movement) and shuffled gait. Anxiety and depression also seem to be common in advanced stages of Parkinson s disease. In addition to the motor symptoms, the cognitive function of the brain is also compromised.

Degeneration of the nerve cells in the substantia nigra of the brain results in the reduction in production of dopamine which is a neurotransmitter in the brain. Neurotransmitters relay impulses from one nerve to the other. This is what is mainly responsible for the motor symptoms in Parkinson s. Although, Parkinson s is not a curable disease, it can be controlled and the progress of the disease can be kept in check with certain medications.

What causes Parkinson s disease?
The cause of Parkinson s is mostly idiopathic, i.e. the cause is unknown and is not specific. However, there have been cases which show that it can be attributed to factors such as genetic and environmental factors.
What are the symptoms of Parkinson s?

The symptoms of Parkinson s can be classified as Motor symptoms and Non-motor symptoms:

Motor Symptoms 

Bradykinesia: Slow movement
Tremor of limbs
Rigidity or stiffness of trunk and limbs
Impaired balance and difficulty in coordination or postural instability
Non-motor Symptoms 

Depression
Anxiety and fear
Loss of energy and fatigue
Constipation
Excessive salivation
Weight gain or weight loss
Cognitive problems such as difficulty in remembering, confusion, dementia
Parkinson s disease is not curable, but when detected early, medicines are prescribed to give symptomatic relief. Dopamine substitutes are prescribed to the patient to relieve the motor symptoms.

Parkinson's Disease - Understanding The Motor & Non-motor Symptoms!

Sleep apnea is a potentially dangerous sleep disorder in which you stop and start breathing frequently while you are sleeping. Symptoms of sleep apnea often include loud snoring and fatigue even if you sleep uninterrupted through the night. Obesity and age are the common risk factors of sleep apnea.

The most common type of sleep apnea is obstructive sleep apnea, in which the throat muscles contract and relax while you are asleep. The other type of sleep apnea, called central sleep apnea, usually occurs in people who have been diagnosed with brain tumors, infections or heart failure, or have had a stroke.

Treatment of sleep apnea includes:

CPAP: The Continuous Positive Airway Pressure (CPAP) device is generally recommended in the treatment of sleep apnea. CPAP is a breathing machine that stops your airways from getting blocked when you are sleeping. The CPAP device is normally the size of a tissue box. It comes with a mask that you put over your mouth and nose. The machine attached to the mask pumps a continuous flow of air that keeps your airways clear as you sleep.
BPAP: The Bilevel Positive Airway Pressure (BPAP) device is used as an alternative to the CPAP device, if you find it hard to adjust to the CPAP. If you have a weak pattern of breathing, the BPAP can be helpful.
ASV: The Adaptive Servo-ventilation (ASV) device is used to treat both central and obstructive sleep apnea.
Treatment for other medical conditions: Sometimes sleep apnea can be caused by underlying health conditions. Problems such as rhinitis (nasal passage inflammation) and hypothyroidism (underactive thyroid gland) can cause sleep apnea. In such cases, your doctor needs to diagnose these conditions first before treating your sleep apnea.
Lifestyle changes: Excessive weight sometimes can cause sleep apnea; so losing excessive weight should be a priority. Also, alcohol and tobacco can contribute to your symptoms, so try avoiding those.
Medication: Usually, doctors do not prescribe any medicine, since sedatives and sleeping pills actually worsen sleep apnea. But, in case of sleep apnea in children, doctors typically suggest intra nasal corticosteroid medicine to treat the symptoms.
Surgery: Surgeries to increase the size of your airway or to remove your adenoids, tonsils or extra tissues in the rear of your throat or your nose can prove helpful.

A brain tumor can occur at any age and it generally occurs in people in the age group of 40-60 years. The common types of brain tumor are termed as meningioma and gliomas. These supratentorial brain tumors generally occur above the covering of the cerebellum tissue. In children, brain tumors occur at the age of 1-12 years and the most common tumors are ependymomas, astrocytoma and meduloblastomas. Brain tumor is the common cause of death even in children.

Tips to Detecting a Brain Tumor

The general symptoms that are indications of a brain tumor include severe headaches, memory changes, nausea, drowsiness, sleep problems, fatigue and sudden involuntary movements of muscles of an individual. The symptoms can be either specific or generic and the general symptoms are mainly caused by the pressure of the tumor on the brain. The specific symptoms on the other hand are caused when specific parts of the brain does not function properly. Many people even experience loss of control of body functions.

The other problems that are experienced by individuals include changes in the ability to perform daily activities and loss of balance. They find difficulty in hearing, speech and at times are very aggressive. If these symptoms exist, then your doctor would recommend a physical examination and ask about your health history and that of your family.

Tests to Detect Brain Tumor
The tests that are advised by doctors to detect a brain tumor include MRI, neurologic exam, CT scan, biopsy, angiogram and spinal tap.

In the neurologic exam the vision, alertness, hearing, coordination, muscle strength and reflexes are checked by the doctor. The doctor also checks for any swelling in the eyes which can be caused by the pressing of the nerve which connects the brain and the eye.

The CT scan done for detecting brain tumor provides detailed pictures of your head and it is done through an X-ray machine which is connected to a computer. The contrast material is injected into the blood vessel of your hand and abnormal areas can be seen easily.

Biopsy
In this method tissues from the brain are removed and tested for tumor cells. The cells are observed by a pathologist under a microscope mainly to check for abnormal cells. The biopsy method is used to show tissue changes that can further lead to cancer. Brain tumor can be easily diagnosed with this method.

MRI:
Magnetic Resonance Imaging or MRI as it is commonly referred to is of great use as it helps to diagnose brain tumors. In this procedure, a dye is injected through a vein in the arm using which the variances in the tissues of the brain can be identified.

Tips For Detecting A Brain Tumor!

Cerebral palsy is a neurologic condition that occurs in children, and is due to brain injury that develops before, during, or after childbirth. The condition presents with motor impairment, and therefore there is generalized physical and mental dysfunction. The brain continues to develop for the first two years of life, and so conditions like premature birth, asphyxia at birth, and postnatal meningitis and encephalitis.

The diagnosis could be trigged by the slow motor development, poor muscle tone, and delayed response of the baby. One of the main noticeable feature that becomes evident is the spasticity of the limbs. The child may not be able to voice it out, but pain is a significant disabling factor too. While doctors would advise that physical movement is required to keep the spasticity at bay, the pain keeps the child away from most activities. This further adds to the spasticity and worsening of the condition.

Pain control therefore assumes a significant role and the modes can range from physical therapy to pain killers to injections to surgery. The idea, in addition to pain control, is also to:

Improve range of motion
Improve motor response
Promote good motor development
Reduce and control contractures
Improve overall lifestyle
Improve muscle strength
Improve exercise tolerance
Reduce spasticity
Some of the non-medical ways to control pain are listed below. 

Of course, pain killers and injections are always used when immediate relief is required. A structured physical therapy program that includes medications and exercise is the best way to manage cerebral palsy pain. Though initially difficult, over a period of time, it improves range of motion and improves joint movement.

Acupuncture: Triggering specific points via needles is believed to stimulate the nerve endings and help in pain control
Alternating ice and heat therapy: This is also believed to improve pain control, blood circulation, and muscle movement.
Positioning in bed: A well-positioned child in bed may have less pain compared to another child who is not. Special equipment may be used also to keep the child in place, once the most comfortable situation is located.
Muscle massage: The affected muscles need to be massaged repeatedly so that blood flow improves, joint movement is better, and pain is controlled.
Botox is successfully used to pain control, as it paralyzes the specific muscles along with providing pain control.
Medications are used regularly, which are mainly anticholinergic and anti-spastic medications. They reduce stiffness, control pain, and help in pain control too.
Surgery is the last option and needs to be explored with the doctor.
