The Problem

Alzheimer ‘s disease ( AD ) can besides be called as Alzheimer disease, Senile Dementia of the Alzheimer Type ( SDAT ) or shortly as Alzheimer ‘s. This disease is a really common signifier of dementedness. Dementia is characterized by loss of or decrease in memory and other cognitive abilities. It is caused by assorted diseases and position that consequence in damaged encephalon cells.

When a individual is affected with Alzheimer disease, synapses of nerve cells will get down to neglect to reassign information. This will go on with more decline of synapses and impairment of cells. Brains with advanced Alzheimer ‘s show rapid shrinking from loss of cells and distributed dust from dead and dying nerve cells.

The image from hypertext transfer protocol: // show a comparing of image utilizing PET scans between mild Alzheimer ‘s and normal encephalon. a patient that face greater sum of linguistic communication disfunction than jobs with spacial sight show a important decrease in metamorphosis in left frontlet, temporal and parietal lobes. If there is greater ocular damage, the image will hold a diminished glucose metamorphosis in the right parietal lobe.

Alzheimer ‘s disease is categorized as a primary intellectual disease of unknown etiology feature of neuropathological and neurochemical characteristics. During the oncoming, it is normally insidious and easy developing steadily over 2 to 3 old ages but can at times be well longer. The oncoming is recorded to be in the center of big life or earlier ( Alzheimer ‘s disease presenile oncoming ) , but the incidence is much higher in later age ( Alzheimer ‘s disease of doddering oncoming ) . Presenile onset patients are largely with oncoming before the age 65-70. There are much higher opportunities of early oncoming in people with a household history of a similar dementedness, features of temporal and parietal lobe harm such as dysphasia or dyspraxia. On the other manus, another oncoming class is much slower and to be characterized by more general disablement of higher cortical maps.


The image from hypertext transfer protocol: // shows portion of the encephalon that has been shaded harmonizing to its map. This is the portion that is affected by the Alzheimer disease.

From hypertext transfer protocol: //, the abilities that are affected by Alzheimer ‘s are:

1 ) Ability to organize consistent address or intelligibly address or


2 ) Ability to place or acknowledge objects, presuming integral

centripetal map

3 ) Ability to execute motor activities, presuming integral motor

abilities, centripetal map and comprehension of the needed


4 ) Ability to believe abstractly, make sound judgements and

program and carry through complex occupation

aˆ? The diminution in cognitive abilities must be terrible plenty to

interfere with day-to-day life.

hypertext transfer protocol: // explain that characteristic alterations in the encephalon when a individual is said to be Alzheimer ‘s patient: a pronounced lessening in the figure of nerve cells, particularly in the hippocampus, substantia innominata, venue ceruleus, and temporoparietal and frontal cerebral mantle ; visual aspect of neurofibtilly tangles made of mated coiling fibrils ; neuritic ( argentophil ) pestilences, which consists of mostly of amyloid and demo an obvious patterned advance in their development ; and granulovacuolar organic structures. Neurochemical alterations can besides be seen besides a pronounced decrease in the enzyme choline acetyl-transferase, in acetylcholine and other neurotransmitters and neuromodulators inside our encephalon.

Alzheimer Disease is still incurable boulder clay now.

Problem Solution

Alzheimer ‘s Association has made a bill of exchange of some of the drugs which are used and has been the lineation for Medicare National programs do cover for the drugs. At present, there are merely 2 types of medicines which have the blessing by the U.S Food and Drug Administration ( FDA ) for intervention of cognitive symptoms of Alzheimer ‘s disease.

Based on hypertext transfer protocol: //, medical professionals have divided the intervention into 2 classs which fundamentally based on the symptoms of the Alzheimer ‘s patients which is cognitive symptoms and behavioural and psychiatric symptoms.


Treatment for cognitive symptoms

Memantine ( Namenda )

At 5-hydroxytryptamine ( 5-hydroxytryptamine, 5-HT ) receptors, memantine Acts of the Apostless as non-competitive adversary which will bring forth stronger consequence than what happening at NMDA receptor. So by and large, this drug will regulate the glutamate reaction ( another chemical courier of import for larning and retrieving ) in the patient ‘s organic structure. The chemical courier, glutamate will non be in extra in instance of cells damaged by Alzheimer ‘s disease. Attachment of glutamate to cell surface “ dock sites ” called NMDA ( N-methyl-D-aspartate ) receptors will let Ca to flux freely into the cell. After some clip, this will take to critical overexposure to Ca and causes figure of cell being damaged even faster. Different with the presence of memantine, the destructive concatenation of events will be prevented by partly barricading the NMDA receptors.

At different neural nicotinic acetylcholine receptor ( nAChRs ) , memantine will move as a non-competitive adversary which at authorities about similar to the NMDA and 5-HT3 receptor. However, this is still in uncertainty as it is really hard to determine with truth because of the rapid desensitisation of nAChR in figure of experiments. As most patients of Alzheimer ‘s suffered neurological devolution, this has been ever related to the glutamate receptors which finally over activated that turnout to be awful.

Cholinesterase inhibitors

Drugs that normally been prescribed based on Alzheimer ‘s Association are donepezil ( Aricept ) , rivastigmine ( Exelon ) and Galantamine ( Razadyne ) . The chief map of these drugs being prescribed are to do certain acetylcholine degree at highest as possible and detain the deterioration of encephalon map every bit long as possible.

One of the drugs, rivastigmine for case, is used to suppress both butyrylcholinesterase and acetylcholinesterase. By suppressing both of these enzymes, there will be less acetylcholine that is degraded therefore maintaining the acetylcholine degree at safe. It is of import to maintain the degree high plenty as they play an of import function in linking the peripheral nervus system ( PNS ) with cardinal nervus system ( CNS ) . By making this, Alzheimer ‘s sick person communications among nerve cells are supported and some clinical tests even show dramatical consequences.

This drug nevertheless has some side effects such as sickness, purging, diarrhoea, anorexia and weight loss. Rivastigmine is seen to hold stronger side effects than the other because of its strong authority of its double inhibitory mechanism. However the effects have been decreased after the introducing of rivastigmine spot that has more stable and consistent active ingredients than the unwritten method.


Galantamine ( Razadyne, Nivalin, Reminyl ) is a type of chemical used to handle mild to chair Alzheimer ‘s disease and in the interim with legion memory amendss. It is believed that this drug which really a type of carbamate ( ester from carbamic acid, NH2COOH ) will diminish the rapid memory harm because of presence of cholinesterase enzyme that capable of interrupting down acetylcholine. By suppressing the enzyme, the degree and the action of neurotransmitter acetylcholine can be increased or at least at changeless and without farther decrease. In the other word, this drug works by additions cholinergic map by increasing the concentration of acetylcholine in the encephalon.

Donepezil ( normally misspelled as donezepil is besides called as E2020 ) is mainly map as reversible acetylcholinesterase inhibitor. This drug is majorly to handle some cognitive symptoms in Alzheimer ‘s patients such as sleep apnea, autism, and others. The drug works by additions the degree of acetylcholine which is a type of encephalon chemical. For the record, donepezil is the lone drug that is approved to be prescribed for advanced Alzheimer ‘s disease patients.

The effects that have been detected normally are purging, sickness, loss of appetency, increasing intestine motion frequence.

Treatment for behavioural and psychiatric symptoms

A.Medications that are presently being used are ; –

Antidepressant medical specialties for low temper and crossness:

Citalopram ( Celexa )

Fuoxetine ( Prozac )

Fluoxatine ( Prozac )

Paroxeine ( Paxil )

Accumulative Word:

Minor tranquilizers is used for anxiety, restlessness, verbally disruptive opposition and demeanor:

Oxazepam ( Serax )

Lorazepam ( Ativan )

Antipsychotic drugs specifically for psychotic beliefs, aggressiveness, agitation, hallucinations, ill will and uncooperativeness. Example of drugs from hypertext transfer protocol: //

Aripiprazole ( Abilify )

Clozapine ( Clozaril )

Haloperidol ( Haldol )

Olanzapine ( Zyprexa )

Quetiapine ( Seroquel )

There are some tips and indexs from the authoritiess and counsel to utilize the medical specialty on the persons with alzheimer ‘s:

The patient ‘s behavioural symptoms are due to mania or psychosis

The residential is sing grim agony or disconsolate, a important decrease in map or significant trouble having needed attention

The symptoms that present is a danger to the people around and occupants

A individual with dementedness should non be sedated or restrained by antipsychotic medicines. The minimal dose should be usedA for least period of clip possible. Countrary side effects must be monitored carefully.

Eventhough this drugs are often used medicines for agitation, doctors would besides order a temper stabilizer or ictus medicine, such as:

Divalproex ( Depakote )

Carbamazepine ( Tegretol )


Treatment for kiping alterations in a individual with Alzheimer ‘s

Non-drug intervention

The chief aim of this intervention is to better the sleep modus operandi and environment besides cut downing the patients ‘ daytime napping. This intervention is more preferred than through medicines because it does non hold side effects like each of medical specialty does. The intervention is done by making contributing sleeping environment and promote the Alzheimer ‘s patient to rest at right clip such as:

Alcohol, nicotine, and caffeine is prohibited

Time ordinance is maintain for repasts and for traveling to bed and acquiring up

Any hurting must be treated

Medicine before bedtime is disallow for patient who are taking cholinesterase inhibitor

Puting comfy temperature room

Watching telecasting during wakefulness must be discourage

Nightlight and safety objects are provided

Regular exercising is encouraged, but non subsequently than 4 hours before bedtime

Promote forenoon visible radiation exposure

If the individual awake, the patient is discouraged to remain on bed. Merely used bed for slumber

Medicines intervention

There are some instances non-drug intervention fail to reconstruct the sleep alterations or some of them are followed by riotous nighttime behaviours. Experts recommend the patient to hold a intervention with “ get down low and travel slow. ” The hazard intervention for older patient who is cognitively impaired must be put in consideration. This is including hazard of falls and breaks, confusion and decrease in the ability to care for oneself.

When the medicine is conducted, it must be discontinue when the slumber form has restored and stable to normal. An utmost cautiousness must be put on when a determination to used antipsychotic drug is being considered. Such drugs even have been put with a labeled of ‘black box ‘ warning about their hazard and that they do non hold the blessing from FDA to handle dementedness symptoms.

From hypertext transfer protocol: //, the drugs that are still being used:

Older “ classical ” major tranquilizers such as Haldol

Tricyclic antidepressants, such as Pamelor and Desyrel

“ Sleeping pills ” such as zolpidem, zaleplon and chloral hydrate

Benzodiazepines, such as Ativan, Serax and Restoril

“ Atypical ” major tranquilizers such as risperidone, onlanzapine and quetiapine


Options Solution

There is still no absolute lasting intervention for Alzheimer disease. Even though there are some good developed medical specialties that are prescribed and approved by the governments such as United States Food and Drugs Administration ( FDA ) and World Health Organization ( WHO ) , there are still some research workers that demoing some other options solutions which literally help to handle Alzheimer ‘s disease.

Picture A Picture B

Picture A from hypertext transfer protocol: // and image B from hypertext transfer protocol: // shows the package of neurozan.


This latest innovation has grabbed all the eyes of medical professionals from full universe. This new medical specialty contained Numberss of foods which chiefly to increase encephalon map and memory to optimum degree as it is specially made for Alzheimer ‘s patients. This drug have phospholipids phosphatidylserine, phosphatidylcholine and lecithin, co-enzyme Q10 ( CoQ10 ) , docosahexaenoic acid ( DHA ) , B vitamins, antioxidants, minerals and amino acids.A A

Docosahexaenoic acid ( DHA ) is an omega 3 fatty acid which capable of assisting to increase the velocity and efficiency transmittal of impulse along nerve cells. The benefits achieve when the powerful omega 3 from neurozan concentrated into medulla sheath which is an insulating bed that forms around nervus cells.


B vitamins that are chiefly concerned in handling Alzheimer ‘s patients are B2, B6, B12, and folic acid. Because of this initiation, B vitamins are added in neurozan. This initiation besides said that B vitamins are critical to work together with homocysteine that at normal degree. Homocysteine is an amino acid that is a non-essential protein which means of course made in human organic structure. Normally, homocysteine will be converted into two chief encephalon foods which are full of benefits. The foods are glutathione and S-adenosylmethionine ( SAMe ) . However, the transition can merely be done in equal sum of B vitamins. If it is non plenty, the enzyme to change over homocysteine to these encephalon foods will non work decently. As a effect, homocysteine will increase in extra and increases chances of peripheral vascular disease ( peripheral arterias ) , coronary bosom disease and shot. So, equal sum of B vitamins in day-to-day diet is of import to guarantee our encephalon can work at optimum.

Vitamin E

Vitamin E has a natural antioxidant that is said to hold a protective function which might assist forestall any harm to the encephalon by free groups. Normally cell will work and produces a by-product called a free group. This substance will destroy any familial stuff and cell constructions, nerve cell to be specific. The harm it made is called oxidative emphasis and it is believed that this is why Alzheimer ‘s disease develops good in a patient. However this vitamin E do non hold a solid cogent evidence to forestall or slower the advancement of Alzheimer ‘s disease yet but there are some positive consequences that suggest high dosage of vitamin E may ensue in some mild functional betterment but non cognitive betterment.

Ginkgo Biloba

This works is well-known for its great memory and concentration foil effects. Its infusion contains compounds that able to positively impact the cells encephalon and organic structure cells. This infusion is understood to hold antioxidant and anti-inflammatory belongingss which enable the infusion to forestall decrease of cell membranes and act as neurotransmitter map regulator. This has been the ground why in Europe, people utilizing the infusion to relieve cognitive symptoms which connected to the figure of neurological conditions.

However, this works has a side consequence, it will do addition blood flow particularly at encephalon country. Any accident that can do hemorrhage can be hazardous which has chances of decease. Some probe on the efficiency of this works ‘s infusions to bring around Alzheimer disease is still can non be proven.
