Is Parkinson disease curable? What is the reason behind this disease and what are the symptoms of it? Are there any precautions that are supposed to be take care in this disease? Please suggest.
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
- 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
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
Stroke is a fatal brain disease and can cause permanent damage to your system so its best to check with your Neurologist to know how you can prevent it.
Epilepsy is a disorder of the central nervous system, thus it is basically a neurological disorder. In this the nerve cell activity of the brain is disrupted and causes seizures along with episodes of unusual behavior along with the loss of consciousness. The symptoms of the seizure can vary and some people with epilepsy just stare blankly for few seconds when a seizure takes place, while some twitch their arms and legs repeatedly.
Symptoms of Epilepsy:
As epilepsy is caused by the abnormal activities in the brain cells, seizures affect the processes with which the brain coordinates. Some signs and symptoms are:
- Staring blankly
- Confusion which is temporary
- Uncontrolled jerking movements of the legs and arms
- Loss of awareness and consciousness
- Psychic symptoms
Mostly the symptoms vary depending on the type of the seizure. The seizures are further classified into focal and generalized depending on which part of the brain shows abnormal activity.
When seizures are due to the abnormal activity of the cells in just one area then it is known as focal seizures. These seizures are of two types:
- Simple partial seizures or the focal seizures without loss of consciousness. These seizures basically alter the emotions and the things like change in smell, look, sound and taste. These also result in the involuntary jerking of the body like the legs and arms, with spontaneous sensory symptoms like the tingling and flashing of the lights.
- Complex partial seizures or the focal dyscognitive seizures. These seizures have a loss of awareness and consciousness. One might just stare blankly into space in this seizure and performs repetitive activities like swallowing, chewing, walking in circles and chewing.
There are six types of generalized seizures. These are:
- Absence seizures, also known as petit mal seizures, are commonly seen in children and are characterized by subtle body movements like lip smacking and eye blinking and staring blankly into space. These also cause loss of consciousness.
- Tonic seizures lead to stiffening of the muscles. These affect the muscles of the legs and arms and also cause to fall to the ground.
- Atonic seizures are also called as drop seizures. These cause loss of control in the muscles, thereby leading to collapse or fall.
- Clonic seizures are the rhythmic and jerking muscle movements. These affect the arms, face and neck.
- Myoclonic seizures appear as twitches in the arms and legs.
- Tonic-clonic seizures also known as grand mal seizures are very dramatic and lead to body stiffening, abrupt loss of consciousness, shaking and loss of bladder control and tongue biting. If you wish to discuss about any specific problem, you can consult a neurologist.
I was suffering from slip disc from 10 days. Now I am feeling better after take rest but now when I turn down in front I feel pain in my right hips mussels. What should I do.
I am 37 years old male. From past 2 years, I have migraine like headache mostly arising due to too much sound near me. Sometime also due to empty stomach. No history of hypertension and diabetes. I am not sure when it will start. It start any time of the day or night. Goes only after taking head ache pill like disprin. Kindly suggest is this symptoms of migraine or because I am empty stomach, this headache starts? What should I do in such situations?
My only son is cerebral palsy he is now taking valparin syrup thrice a day and zapiz. 25 mg twice daily for his past seizure history bt after 2002 he has not any seizures. He is now near about 20 years of age. My question is whether he should continue this medications life long? If we discontinue it may seizure will occur again?
I have problem of fits .I take treatment and my EEG and MRI also normal .so what is the cause behind it?
Getting hallucinations is a mental condition where a person sees, feels, hears, and tastes things that actually don't exist beyond one's heightened imagination or delusion. It involves the experience of perceiving something not present. Hallucinations can be pleasing or frightening. However, there is almost always an identifiable cause behind it.
They can be triggered by:
- Taking hallucinogenic or psychotropic substances
- Mental conditions like dementia and schizophrenia
- Neurological conditions like Alzheimer’s disease or Parkinson's disease
- Macular degeneration, leading to loss of vision
- Migraines and brain tumor can also lead to such delusions
Some of the signs of hallucinations:
- Hearing voices: The medical term for hearing voices is called an 'auditory hallucination'. A person may sense sounds or noises coming from inside or outside of their mind. The noise might be random or disrupting. One might also feel the voices talking to each other or trying to tell them something. Most of the times, these voices come from inside the person's mind; or in some cases, one's heightened perception may make a normal noise delusional.
- Seeing things: This is also called visual hallucinations. For instance, one may see unnatural things like a floating chair in thin air. It all depends on a person's perception. Sometimes these hallucinations appear as bright flashy spots or rays of light.
- False sense of taste and smell: Technically, these are known as gustatory and olfactory hallucinations respectively. One may feel a kind of odor coming from one's body or surrounding; or a person might feel that something he/she is drinking or eating has an odd taste. This is again too much thinking, causing delusional sensory activities.
- Tactile hallucinations: This is when a person feels things that don't exist. One may feel that he/she is being touched or tickled even when no one else is around or that insects are crawling beneath the skin. One may experience strange sensations, which are not a part of a reality. If you wish to discuss about any specific problem, you can consult a psychiatrist and ask a free question.
When it comes to the brain and IQ, is bigger better? Does size really matter? Is there really a connection between the size of your brain and intelligence? With the help of findings by neurologists and scientists, we seek to find out!
- Ailments and the brain: Scientists have found that children with autism have a brain that has grown in a disproportionate manner in the very first year of their life. This prevents the child from making connection in a normal manner. On the other hand, children and adolescents who suffer from Attention Deficit Hyperactivity Disorder or ADHD show sign of having a much smaller brain size. Many scientists have shown that the size of the brain shrinks as we age and this does not have any visible effect on our cognitive abilities.
- It’s all relative: The size of the brain does not really have a bearing on the way a person’s cognition gets shaped. Even large mammals like elephants and whales are finally hunted and tamed by humans who have smaller brains in comparison. The brain is made up of billions of neurons, which need to function properly. It may be seen that scientists consider the brain mass in relation with the rest of the body so as to speculate about the cognitive abilities of the person. Why is this required? Large animals need a well functioning and proportionate brain size to control and run their organs with proper cognition for satisfactory results, which is what we humans seem to have done.
- Neanderthal brain: Historically, the earliest man or the Neanderthals are said to have had larger brains than we do. These people are believed to have brains that are at least 10% larger than the brains that we have in our modern times. The shape of their brain was different too. They were also heavily muscled people which had a bearing on the size and shape of the brain and bodies as well as the lean tissue within the brain. They also survived very successfully for a period of over 200,000 years, which obviously points to some form of elevated cognition, as per many scientists.
- Animals: While animals with small brains like lizards and reptiles do not perform too well on IQ tests, the animals with bigger brains like elephants and dolphins perform much better. But the medium sized brain of monkeys, lemurs and other animals are said to perform in the best manner. The correlation between the body size and the brain does not seem to hold good here, as per various researches.
So the verdict as per medical science and research stands divided! If you wish to discuss about any specific problem, you can consult a doctor and ask a free question.
