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

The brain contains numerous nerve cells which help in its normal functioning. Epilepsy or seizures occur when there is a disruption in the activity of the nerve cells in the brain. A neurological disorder of the CNS (Central Nervous System), epilepsy can affect all and sundry, irrespective of their age, sex and ethnicity. However, children and aged people (above 60 years) are more susceptible to the condition. A study suggests approximately 10 million people in India suffer from epilepsy.

Types of Epilepsy
Based on the activity of the brain that causes an epileptic attack, Epilepsy can be of two types - Focal or Generalized
Focal Epilepsy: An epileptic attack triggered by unusual activities restricted to a particular area of the brain.

In some cases, focal epilepsy may result in unconsciousness. A person may also lose awareness and become unresponsive (keeps staring into space), a condition termed as Focal Dyscognitive Seizures. A person with this condition may behave strange, such as walking in circles, chewing or rubbing their hands.
In another type of focal epilepsy known as Focal seizures without loss of consciousness, a person does not lose consciousness. In such cases, there may be sudden and involuntary jerking of the arms or the legs. There may also be dizziness or a tingling sensation.
Generalized Epilepsy: Here, the seizures or epilepsy result from unusual activities throughout the brain. Generalized epilepsy, may, in turn, be of the following subtypes

Tonic seizures: This affects the muscles of the legs, arms, or the back, causing them to stiffen and tighten up.
Atonic seizures: Here, a person may suddenly fall down due to loss of muscle control. The condition is also known as Drop Seizures.
Absence seizures: Mostly affecting children, the affected person may lose awareness (temporary) and behave strangely such as staring into spacing, smacking their lips, or blinking their eyes continuously.
Clonic seizures: They are characterized by sudden and continuous jerking movements of the arms, face, and neck muscles.
Tonic-clonic seizures: Here, a person may suddenly lose consciousness. There are violent shaking and stiffening of the body. Some people may even be seen biting their tongue.
Myoclonic seizures: In this arms, and legs of a person suddenly twitches and jerks.

What triggers an Epilepsy?
Epilepsy may be an outcome of the following factors

Medical conditions such as stroke or even brain tumors may affect the normal activities of the brain, thereby resulting in epilepsy. Diseases such as Viral Encephalitis, AIDS or Meningitis act also act as a trigger, accelerating the chances of epilepsy.
Developmental disorders such as Neurofibromatosis or Autism can also trigger epilepsy.
In some cases, epilepsy may be a genetic predisposition. Thus, a person with a family history of epilepsy may suffer from the condition.
Epilepsy may also be an outcome of a prenatal brain injury due to oxygen deficiency or an infection to the mother.
People with dementia may also suffer from an epileptic attack.

Autism is a developmental disorder that is usually diagnosed within the first three years of a child s life. Speech disorders and an inability to communicate with others are characteristic symptoms of autism. Speech therapy can be very beneficial for such children. Thus, it is often a major part of a treatment plan for autism. Some of the benefits of speech therapy for autistic children include:

Better articulation: Autistic children often find it hard to make certain sounds. Hence, they tend to babble or make harsh sounds or grunt instead of talking. A speech therapist can help the child learn to articulate sounds in a better way. For this, the therapist will help the child exercise the facial muscles and lips. This can make it easier for them to be understood by others.
Treating echolalia: Echolalia refers to a child s behaviour where he or she answers a question by repeating part of it. This may be because they find it difficult to express their own thoughts and feelings. Echolalia is very common amongst autistic children. Speech therapy is the only way to treat this condition. If left untreated, it could make the child withdraw into himself.
Better vocabulary: Autistic children often memorize words without understanding them. A speech therapist can help the child put words into context and thus help reduce their dependence on gestures. This can also make autistic children more confident. In addition to expanding their vocabulary, a therapist can also teach children the proper time and place for communication. For example, when to say good morning and good evening.
Initiate communication: When children are not confident of expressing themselves, they wait to be called on before saying anything. By helping them articulate sounds better and expanding their vocabulary, a speech therapist can help children gain the confidence needed to initiate conversations. With therapy, autistic children can also follow simple instructions and begin to answer questions independently. This will make them more independent.
Speech therapy does not follow the same techniques for all children. For therapy to be effective, the therapist must work in close collaboration with the child s parents and caregivers to set the right goals and monitor the child s progress. Some of the techniques that may be used include the use of electronic talkers, typing or signing, picture boards, facial exercise and massages, using rhyme to help construct sentences and using sounds to help the child expand speech sounds. If the child is non-verbal, the therapist may also introduce alternatives to verbal communication.

Can Speech Therapy Help Autistic Children?

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.

Sleep Apnea - 7 Ways it Can Be Treated!

Sleep disorder is a serious problem which a large number of people are facing due to multiple reasons. Almost every other person complains of having some sort of sleep disorder, irrespective of his/her age.

Sleep is the normal physiological process of our body which is as important as respiration and digestion. Sleep is vital for maintaining our physical and mental health. Normal adults require 8 hours of sleep every day, whereas it 14 to 15 hours of sleep is recommended for for infants and toddlers.

What are the different stages of Sleep

Every human has a natural circadian clock in their body, which is responsible for maintaining our sleep - wake homeostasis. The different stages of sleep include REM and NREM that is rapid eye movement sleep and non rapid eye movement sleep respectively. REM is the deep sleep stage in which it is very difficult to wake up the person as this stage includes the sensory inhibition and all voluntary muscles along with almost all interactions with the surroundings are inhibited. Therefore, a person s physical stress and tiredness also gets relieved during this stage of sleep. NREM sleep is the stage between REM and awakening and here the person may have sensory connection with his or her surroundings, but may not respond.

Sleep and its benefits
Sleep and stress have a very strong connection with each other. The best way to relieve stress and any other mental disturbance is sleep. It is essential to have knowledge about sleep psychiatry for almost all physicians as they face many sleep deprived patients in their day to day practice.

    Sleep is not only responsible for relieving mental stress and depression, but has other benefits as well
    Sleep is also essential for the normal physiological growth in early infancy and it is vital for development of normal alertness, attention and knowledge
    It also relaxes our voluntary muscles and thereby, relieves us from physical stress
    Sleep disturbance may also aggravate diseases in our body. Sleep is also the state of recovery and healing.
