One of the worst neurological disorders to have is dementia. It is a general term used to describe cognitive decline of the brain. It s not specific disease but denotes several brain disorders and mental illnesses. A person suffering from dementia can have severe impairment in judgment, loss of memory and thinking. Dementia is a very difficult disease not only for the patient but also for their families and caregivers. 

Some facts about dementia are as follows:

It s not a mental disorder occurring in old age but it does degenerates with age.
An estimation of 47.5 million people worldwide suffers from dementia and 60% of these people live in low and middle-income countries and according to WHO this figure is likely to increase.
Every 4 seconds a new case of dementia is reported
Dementia is a collective term to describe the many types of in people, such as 

Alzheimer s Disease: It is one of the most common type of dementia accounting for 60-80% of dementia case. People suffering from Alzheimer s have fewer nerve cells and the size of the brain shrinks.
Vascular Dementia: Another most common form of dementia occurring after a stroke.
Lewy Body Dementia: It is neurodegenerative condition that involves a protein called alpha-synuclein which changes the brain. Symptoms may be similar to Parkinson s disease.
Symptoms of dementia can range from mild to moderate to severe that includes:

Memory Loss
Disorientation meaning inability to focus or pay attention
Changes in visual perception
Impairment in reasoning and judgment
Dementia can be caused by damage to brain cells or progressive brain cell death. As a result communication between brain cells become difficult. Other symptoms include:

Stroke
Brain Tumor
Head Injury
Prion Disease
HIV Infection
Reversible Factors

There are no definite tests for dementia. Doctors and neurologists have to medical history, blood tests and CT scans to find out whether a person has dementia or not. However, the most potent evaluation comes from a set of questions that are asked to a patient suspected of having dementia. The ability to answer those questions correctly is one of the best diagnoses for dementia.
There is no specific treatment for dementia as it is not a curable disease and degenerates with time. However, medicines or drugs given for Alzheimer s can be given to people suffering from dementia.
Although results vary depending upon a person s lifestyle s and habits, doctors suggest eating healthy, exercising regularly, and stopping smoking and drinking may prevent some types of dementia.
The best treatment for dementia is to treat the person with care and love so that they don t feel neglected.
Dementia is often associated with old age but that is not always true. It is important to gain knowledge and educate others also.

Dementia - Quick Facts You Must Know About 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.
Focal seizures
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.
Generalized seizures
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.

Epilepsy - How Seizures Affect It?

Sleep is one such time when people usually are expected to lie down still and get rest. However, we have all heard of sleepwalking, a condition where a person walks during the sleep. Though it may sound strange, there is a deeper explanation for it both from a causative point of view and from managing it.

Things you should know?

Sleepwalking happens when a person moves back from a deep sleep to a light sleep or awakening state.
The person who is sleepwalking is usually not aware of it.
Activities may range from simply getting up and sitting up in bed to walking around the room. They could also open the door and walk out to the neighbourhood. Moving furniture, changing dresses or driving a car, may also be some of the actions Most of these activities happens completely without their knowledge.
Mostly happens in children up to the age of 12, but can be seen in adults also, where it assumes a more severe form.
The person who is sleepwalking has a fixed stare with glassy eyes. They may appear dazed and lost when they are awakened.
They may not respond when they are actually sleepwalking, or respond very slowly
They can be brought back to bed and put back to sleep without being disturbed. Most children would go back to sleeping when this is done
Though the parents can be very worried when they see children sleepwalking, reassurance is required, as it usually disappears as they cross teenage.
There could be chances of small injury like tripping or fall during the sleepwalking episode
Sleepwalkers may be more restless compared to other children during their waking hours
Bedwetting is also quite common in children who sleepwalk
Causes

Inappropriate sleep pattern with lack of sleep for prolonged periods is one of the main reasons for sleepwalking
Stress
Excessive drinking
Medical conditions like heart rhythm problems, acidity, gastric reflux, and seizures
Psychiatric conditions like panic attacks and post-traumatic stress disorder can also lead to sleepwalking
Management

For a parent to see their child walking around in their sleep can be quite disturbing.
Reassurance is required stating that it is just a temporary phase and will not stay beyond the teenage years
Most people do not require any intervention unless accompanied by severe symptoms like going out of the house or driving
Once established, it is advisable to avoid by not drinking too much alcohol, avoiding stress and anxiety and taking precautions like extra-secure locks to prevent sleepwalking and/or other side effects.

Sleepwalking - 11 Things You Must Know!

The relationship between intelligence and brain size, both among people and between various species, has never been precisely well defined. People often believe that their outstanding psychological capacities must mean that they are superior to all animals as far as brain size is concerned. However, it is not true since whales and elephants have much bigger brains than humans and humans have the same brain-to-body mass proportion as mice do.

Here are a number of ways by which the brain size can be determined:

Encephalization remainder: Since it would be against human instinct to admit loss and defeat, researchers have created a measure to determine the brain size called the encephalization remainder. It is the proportion of actual brain mass with respect to the anticipated cerebrum mass for the animal s size (based on the suspicion that bigger animals require somewhat less brain matter with respect to their size, compared to little animals). By this metric, human beings prove to be the best, with an EQ of 7.5 outperforming the dolphin's 5.3 and the mouse's 0.5.
IQ testing: Without a solitary and evident method for measuring intelligence, some improved tests like IQ (Intelligence Quotient) are by and large acknowledged as a moderately decent working device. IQ estimations are not without issues, and there is a great deal of criticism about their significance. IQ testing uses government sanctioned tests, for example, the WAIS III (Wechsler Adult Intelligence Scale). The normal IQ is somewhere around 90 and 110. The scores beneath the normal may demonstrate changing degrees of pathology, for example, marginal intellectual function, or mental hindrance of different severity. Over the normal range is regularly connected with knowledge, splendour, talent, or genius. However, as with computers of a few eras, size and intellect do not precisely relate. Present day portable computers weighing around one or two kilogrammes can store more data and perform a greater number of assignments than supercomputers from the 1980s that used to possess expansive structures. This is a contrast amongst quantity and quality. Numerous scientists now hold the view that it is not the whole brain, which is bigger in a human with a higher IQ, yet rather certain zones that are denser and might be bigger. A fascinating late revelation is that these ranges can be expanded in size and enhanced in usefulness during the course of our life.
NeuroplasticityIt refers to the dynamic procedure of repair and maintenance that our brains are continually experiencing. We are conceived with around hundred billion neurones, yet lose around two hundred thousand a day to a procedure called pruning. As we develop and grow, pathways in the brain that are not required are detached, and the neurones pass on. However, in a compensatory procedure, new neurones are delivered and more detailed associations are built up between neurones that are more dynamic. This is the procedure of de-cluttering, in which our brains develop to work at most extreme effectiveness. If you wish to discuss about any specific problem, you can consult a Neurologist.

Brain Size - How It Is Related With Intelligence?

Although surgery is considered to be the first step of treatment in any form of tumor, but its feasibility depends upon the type, size and location of the tumor. It is not necessary that every kind of brain tumor might require surgery.

Indications of Brain Tumor Surgery
- Diagnosis of the type of tumor by taking a sample of the tumor for laboratory examination
- Complete resection of tumor
- Removal of the tumor as much as possible to slow down its growth and improve the symptoms
- Remove the tumor in order to help other treatment
- Provide direct access for other forms of treatment like chemotherapy, radiotherapy etc.
- To relieve pressure caused by tumor on surrounding structures

Types of Brain Tumor Surgery
The different types of surgery that are performed in cases of brain tumor include the following:

Craniotomy: Craniotomy is the most commonly performed procedure to remove brain tumor along with a piece of bone. The removed bone is replaced and the tumor is sent for histopathology (biopsy). The surgery is performed using a high end microscope by any of the following techniques:
- Extended bifrontal craniotomy
- "Eyebrow" craniotomy (supraorbital craniotomy)
- "Keyhole" craniotomy (retro-sigmoid craniotomy)
- Orbitozygomatic craniotomy
- Translabyrinthine craniotomy

Shunt: A narrow piece of flexible tube with a pressure regulated valve in between is called a shunt. This is used to relieve the intracranial pressure caused by obstruction of the natural brain fluid, Cerebrospinal fluid (CSF) pathway by tumor mass. The procedure involves insertion of a drainage system into the brain to remove or drain excess of blocked fluid into the peritoneal cavity.

Stereotactic surgery: This surgery is done by creating a three dimensional image called stereotaxy using computers. It aims to find out the location and position of the tumor. In fact it can also be done to aid tumor removal, implant radiation pellets or for other treatments.

Embolization: It is a procedure used to reduce the amount of blood supply to a tumor by blocking the blood flow in the selected arteries. It is generally performed before the main surgery.

Endoscopy and endoscope assisted surgery: Endoscope is a tool, which helps to closely visualize the tissue through small openings in difficult to reach areas. This tool can be used in various brain surgeries to precisely reach the target location without damaging the adjacent structures.

Adjuvant modalities to improve outcome: In addition to above mentioned surgeries, following surgeries may also be performed in relation to brain tumor treatment:
- Laser surgery
- Photodynamic laser surgery
- Ultrasonic aspiration
- Fluorescence guided surgery (FGS)
- Electrophysiological monitoring

Coping with Parkinson s disease is not an easy task. Whether you or your loved one is suffering from it, the effect of the disease takes a toll. Other than the fact that it is a degenerative disease and the neurological condition deteriorates over time, the mental trauma that Parkinson s brings; not only to the patient but to the caregiver as well, is a whole chapter on its own. When you are taking care of someone who is suffering from 

Parkinson s disease, it is natural that the emotional upheaval that you may go through will take a huge toll on your health and your mind. It is imperative that you prepare yourself thoroughly, whether you are the patient or the caregiver, about the disease and its treatments.

There is hardly any cure and treatment for the disease. It is still in its research stage and hence, often there is a strong sense of despair that sets in the mind of the patient and their loved ones. It is for this reason you have to prepare yourself to face and fight this disease. 

Here are some tips that may help you to cope with the treatments of Parkinson s disease:

Educate Yourself: Educate yourself about every detail of the disease, specific to the type of Parkinson s that has affected you or your loved one. Ask questions, whether to your doctor or the nurses. Search through the internet, you will get plenty of genuine information. This is necessary as it will prepare you to face the future head-on. You will understand what you are dealing with and how much worse it can get.
Stay Active: If you are the one who is suffering from Parkinson s, then write it down as the golden rule   I will have to stay physically active. Staying active will keep your muscles active and there will be a steady functioning of the nervous system. Staying active gives you the benefit of keeping the muscles at work, ultimately fighting the main symptom of Parkinson s disease. Being physically active is also essential to have a good mental health, both for the patient and the caregiver.
Connect With People: Talk to people, your friends, family members, children, grandchildren and anyone you feel like. If you have any estranged relative, it could be a good time to reconnect. Have wholesome conversations that will influence happy thoughts and encourage you to think and ponder on happy memories. This is crucial as Parkinson s invites depression and you will have to tackle it vehemently.
Talk to a Mental Health Professional: If you feel that you are losing a complete hold of your life and your depression seems uncontrollable, it is time to visit a professional psychiatrist and seek his/her advice in dealing with your troubled mental condition.
