The Different Types Of Memory
Memory, the brain's power to remember things, comes in different forms. Memory is not a tangible thing; it is not possible to 'improve' one's memory, per se. A person can develop his or her memory skills through practice, like playing guitar. A person's memory can be trained through active participation, paying attention to his or her weak areas of memory or remembering things and make a conscious effort to increase the capacity of his or her brain.
Different domains or types of memory exist in the brain. A person can be very adept at remembering events in the past with great detail but forget where they left their wallet or keys. Like a database, memory is organized in different areas of the brain. A person, without effort, can remember their phone number, birthdates, the taste of chocolate, the sound of children playing, the scent of a rose, the knowledge of how to ride a bike, the feeling of fear and the intention to remember to pick up milk on the way home. Cognitive psychologists believe these bits of information are stored in multimodal systems of memory. These domains of memory are useful when considering the process of improving one's memory. Different memory strategies can be employed and matched with different memory tasks, using the knowledge of how pieces of information are encoded on the brain.
Knowledge memory, the information about the world or external things, and personal memory, the information people know about themselves, are two fundamentally distinct domains of memory. In the domain of knowledge memory, information about music, numbers, language, stories or facts are stored. This includes a person's ability to remember words or a subject he or she has studied. Identity memory refers to the ability of a person to match a name with a face, attempting to remember who that person is, where and how that person is known by them and what the details of that person's life are.
Event memory refers to a person's ability to remember whether or not they have done something, where they have put something, when and where something happened to them and remembering dates. Planning memory refers to a person's ability to remember to do something at a particular time or place, whether they can remember to remember to do something, for example, a person having the thought 'I was supposed to do something, I know I told myself to remember it, what is it, why am I standing here?' Skill memory refers to the ability to remember how something is done, a particular task, how to operate a camera, for example.
With personal memory, a person retains autobiographical information, skill information, social information and planning information. Autobiographical memory incorporates information about oneself, what that person's details are that make them unique, the facts of their life, their experiences and their emotions. All of these bits of detail are processed differently and contained in different domains of memory in the brain. A person's memory for emotions can help a person change their mood. When a person has a strong memory for a specific event that they have experienced, the memory includes details specific to that occasion. As humans, we experience much of life in a routine fashion; these memories are contained in a generic memory- one which includes the common elements of the routine experience.

What Six Herbs Can Help You Improve Memory?
Using herbs to improve your memory can sound bizarre. But this way of improving your memory have long been practiced in the United States as well as in other countries around the world.
Egyptians, Greeks, Orientals and the American Indians have all used herbs to enhance the memory. It is said that spicy herbs can boost the cognitive functions of your brain.
Curcumin is an ingredient found in turmeric, which is present in curry. Curcumin works to improve your memory as well as reduces the effects of mental diseases such as Alzheimer's disease.
Ginger is another herb which defends the brain to improve memory. It contains active ingredient called zingerone.
Smelling cinnamon enhances cognitive function and lifts the mood.
Ginkgo biloba is very good herb for improving blood flow to the brain. Take 80 mg, three times a day.
Gotu kola is another herb which increases memory and guards against senility. Take 1/2 teaspoon of the herb in warm water three times a day.
Siberian Ginseng helps support a strong, balanced nervous system as well as assits your body in adapting to stress. Take 250 mg, two times a day.
It is imperative that before using these suggested herbs you make sure they won't have a harmful interaction with any medications you are currently taking. The plan is to improve your memory, not further damage your health.
You do not need to use herbs only by oral ingestion. A popular method to stimulate your brain is by aromatherapy. A number of herbs can be heated in water or as an ingredient in a candle. Aromatherapy, as a low-cost method, clears the mind, sharpens your ability to focus, helps you relax and improves your mood. Two essential oils that are often used for this purpose are rosemary and basil.

When Does Sudden Loss of Memory Occur?
Memory loss can appear either gradually or unexpectedly. Sudden loss of memory can be caused by many factors. First of all, sudden loss of memory may be induced by a head injury. In order to avoid such situations, it is imperative to learn some safety measures. By wearing the seat belt while driving or a helmet while riding a motorcycle, people can prevent damage from being inflicted on the brain.
In some cases, sudden loss of memory appears as a side effect of statin drugs. People who suffer from hypercholesterolemia usually follow a treatment based on statin drugs. Scientists have observed that retrograde memory loss may also be associated to this type of medication.
Instead of following a treatment based on statins, people who have high cholesterol levels are recommended to follow a diet which may help even more their condition. In addition, the diets do not have side effects, if they are followed strictly.
Other factors that appear without a warning and cause sudden loss of memory are strokes. These are usually determined by a very high blood pressure. Tobacco represents one of the substances that increase the risk of stroke, as it diminishes the blood flow to the brain while increasing the overall blood pressure. Smoking tobacco and all the other products based on tobacco have the same dangerous effect. In addition, tobacco causes many other diseases. Vascular dementia represents alterations of the blood vessels.
In the end, this certain disease leads to stroke and to sudden memory loss. The latter condition does not occur in all the cases. Although vascular dementia develops gradually, the memory loss occurs unexpectedly.
Some brain infections may determine sudden loss of memory, too. Meningitis represents the inflammation of the membrane that surrounds the brain. Furthermore, chronic illnesses or health problems that are recurrent can also determine sudden loss of memory. Epilepsy is, as well, a health condition that may precede sudden loss of memory.
Depending on the underlying cause of memory loss and on the treatment used for that certain cause, the memory loss can be either temporary or permanent. This fact is conditioned by many things, so one cannot determine precisely if the memory will be effective again or not. However, people who experience sudden loss of memory can be helped. First of all, these people must memorize less information, so simplifying the environment in which they live can prove to be an effective measure.

Memory Loss, Nerve Damage Caused by Vitamin B12 Deficiency: Pernicious Anemia
Pernicious anemia is due to lack of vitamin B12, which causes progressive nerve damage, forgetfulness, loss of ability to concentrate and abnormal sensations such as burning, itching and loss of feeling. However, many people with pernicious anemia do not have abnormally low blood levels of vitamin B12.
A study in the Journal of the American Geriatrics Society shows that older people have lower blood levels of a chemical called homotranscobalamin II that carries vitamin B12 into the cells, so they need higher blood levels to have normal tissue levels.
Since low-normal blood level of vitamin B12 do not rule out B12 deficiency, the diagnosis of pernicious anemia is often made late in the course of the disease after many people have suffered permanent nerve damage. According to a report in the Archives of Internal Medicine, two percent of Americans over 60 have low blood levels of vitamin B12, but the incidence of vitamin B12 deficiency causing nerve damage in older people is much higher than that, sometimes as high as 50 percent. Therefore, many older people who are diagnosed with senility actually suffer from lack of vitamin B12 which can be cured by taking vitamin B supplements.
Lack of vitamin B12 also can cause heart attacks, so all people over 60 should be screened with blood tests for vitamin B12 and those with normal levels of B12 and symptoms of nerve damage or arteriosclerosis should also get a blood test called homocysteine.
Many people cannot correct their B12 deficiency with diet because they cannot absorb enough B12 from their food.
Almost always, those with a deficiency can a cured by taking a 1000 microgram pill of vitamin B12 once a day. They usually do not need to take injections. Low levels of B12 are also associated with stomach diseases and infections such as Helicobacter pylori.

SODIMM Memory Frequency, Capacity, Timings - How to Balance Your Next Laptop Memory Upgrade
Your laptop grinds under the strain of software memory requirements forcing you to purchase a laptop memory upgrade. The question is, how do you go about buying an upgrade that reaps the most benefits? We'll take a look at this below.
SODIMM Memory Frequency
Regardless of the type of memory, be it SDRAM, DDR, DDR2, DDR3 etc. memory frequency pays a pivotal role in its performance. You see, frequency influences the speed at which bytes can be read and written to and from a SODIMM memory module.
The faster the frequency of a SODIMM memory module, the greater the bandwidth available to your system, thus ultimately the software you run. Some software benefits more than others when more bandwidth is available, nevertheless it's generally a good idea to have more of it if possible.
Of course depending on your model of laptop, it might not be possible to make use of higher frequency SODIMM memory modules. The underpinning for this is simple, while a laptop supporting for example PC2-4200 DDR2 SODIMM memory that runs at 533MHz effective can have a higher rated SODIMM memory module of the same type but higher grade installed (i.e. PC2-5300 DDR2 running at 667MHz), the net result will still be memory that runs at a maximum of 533MHz. This is true unless of course the memory controller in that laptop supports the frequency of the faster memory. Normally laptop manufacturers already install the fastest grade of memory during production..
Should you conclude that your laptop does support faster SODIMM memory modules, it may just be worth upgrading all the installed memory to whatever highest grade is supported. Memory frequency is the number one contributor to memory bandwidth therefore by in large performance. Do note how we wrote "all" the installed memory. You see, for your laptop to run at the faster memory frequency, all installed SODIMM memory must meet this specification thus be of the same grade. If your laptop has two SODIMM memory slots (this is the norm) then in practise both SODIMM memory modules must be identical. For example, in a DDR2 memory based laptop this might be PC2-6400, in a DDR laptop PC3200, in a SDRAM laptop PC133 or any other available combination. Simply follow this line of thought and you'll be okay.
SODIMM Memory Capacity
The amount of memory you have installed in your laptop is what generally speaking ultimately defines how smooth software runs. Consequently, while memory frequency is a key factor to SODIMM memory performance, the capacity of memory installed is fundamental for overall system performance.
How much memory you need is dependent on what software you run. Unfortunately, there's no golden rule that magically works for each and every application out there. Fortunately however there's an old principle that lends a helping hand: more memory always helps. Essentially what this translates to in practise is this: install more memory than you need as this way you're far less likely to run into slowdowns, providing of course the slowdowns are the result of low system memory and not, per se, the processor, graphics card, storage device etc.
Does this sound too good to be true? Regrettably yes, for three reasons. Firstly, buying too much laptop memory will likely aid laptop performance at the cost of upsetting your wallet. Secondly, in an ideal world all laptops, be them new or old, would support the currently maximum capacity of available SODIMM memory modules. Obviously the world isn't an ideal place and thus you can only upgrade to the maximum capacity supported by your laptop's memory controller. Thirdly, if you're running a 32bit Operating System on a laptop supporting 4GB or more of memory then just keep in mind that even though the memory will work, applications will not use the full 4GB. This is a limitation of 32bit addressing, only some of this namespace is available to system memory, the rest must be used for addressing other types of memory within your laptop, for example that of the graphics card. To overcome this on laptops that support it, upgrade to a 64bit Operating System.
Starting to sound slightly complicated? Let's break this down into simple English. What you should deduct from this is as follows: buy as much memory as your wallet and laptop allows but consider the limitations of 32bit Operating Systems. If you plan to upgrade to 4GB or more of memory and have a newer laptop then upgrade its Operating System to a 64bit version. If your laptop supports 4GB but only 32bit Operating Systems then just keep in mind that the maximum your applications will likely see visible thus use is around 3.25-3.5GB.
SODIMM Memory Timings
Computer memory feature what's known as timings. These are numerical values which represent delays in how a SODIMM memory module operates. The actual values vary depending on the type of memory (i.e. DDR2) and whether the given SODIMM memory module is mainstream or a performance part. Such delays control all the types of commands that get executed when your computer issues a read, write or copy command. Such timings are stored on each SODIMM memory module in what's known as a SPD (Serial Presence Detect) chip, located on the same PCB (Printed Circuit Board) as the memory chips.
Because memory timings are ultimately delays then one might think it's logical to assume that lower timings are better. This can be answered as true but only to an extent. You see, there is only so much that these timings can be lowered, even if a SODIMM memory module has been binned as a performance part. This is due to synchronisation issues. Memory timings control how slow or how fast a given operation is processed by a SODIMM memory module. If it's set too fast then the outcome may be unstable operation. At the very least this will cause erroneous software behaviour, or if you're less fortunate a system halt.
Since enhanced memory timings can only contribute so much to real-world system performance (circa 5% real-world performance boost), it's really a case of deciding whether you believe the added speed boost (i.e. slightly more memory bandwidth, somewhat lower memory access latency) is enough to warrant the price premium. Various tests over the years suggest no, even if you install "performance" SODIMM memory, you're not likely to feel the difference in any type of software but benchmarks.
Conclusion
There are some important facts to recall from the above. First and foremost memory frequency plays a pivotal role in memory performance, otherwise defined at the speed at which memory read, write and thus copy commands get processed. The higher the memory bandwidth, the more it indirectly influences overall system performance. Secondly, memory capacity is what directly affects the overall speed of your laptop by having a direct influence on computer performance. The more memory you have installed, the far less likely you are to run into slowdowns caused by insufficient memory resources available to the Operating System and other software. Thirdly, memory timings act as an icing on the cake (for a better term) to both memory frequency and capacity.
The above is the theory, but what should you do when getting ready to buy your laptop memory upgrade? Always get the highest frequency of SODIMM memory your laptop supports by determining the highest speed grade supported by its memory controller. Wherever your wallet permits, also try and upgrade to a healthy amount of memory, above what you're bound to currently use thus leaving yourself some headroom. Do however remember that your laptop's memory controller also limits the maximum capacity you can upgrade to. Finally, where feasible (something you will have to deduce yourself), choose a SODIMM memory module(s) with faster (lower) timings - if performance parts aren't available then the most you will lose is about 5% overall system performance.
