Problem solving consists of using generic or ad hoc methods, in an orderly manner, for finding solutions to problems.

Some of the problem-solving techniques developed and used in artificial intelligence, computer science, engineering, mathematics, or medicine are related to mental problem-solving techniques studied in psychology.

Amnesia, also known as amnesic syndrome, is a deficit in memory caused by brain damage, disease, or psychological trauma.

Amnesia can also be caused temporarily by the use of various sedatives and hypnotic drugs.

The memory can be either wholly or partially lost due to the extent of damage that was caused.

There are two main types of amnesia: retrograde amnesia and anterograde amnesia.

Retrograde amnesia is the inability to retrieve information that was acquired before a particular date, usually the date of an accident or operation.

In some cases the memory loss can extend back decades, while in others the person may lose only a few months of memory.

Anterograde amnesia is the inability to transfer new information from the short-term store into the long-term store.

People with this type of amnesia cannot remember things for long periods of time.

These two types are not mutually exclusive.

Both can occur within a patient at one time.

Cognition is "the mental action or process of acquiring knowledge and understanding through thought, experience, and the senses." It encompasses processes such as knowledge, attention, memory and working memory, judgment and evaluation, reasoning and "computation", problem solving and decision making, comprehension and production of language, etc.

Human cognition is conscious and unconscious, concrete or abstract, as well as intuitive (like knowledge of a language) and conceptual (like a model of a language).

Cognitive processes use existing knowledge and generate new knowledge.

The mind is a set of cognitive faculties including consciousness, perception, thinking, judgement, and memory.

It is usually defined as the faculty of an entity's reasoning and thoughts.

It holds the power of imagination, recognition, and appreciation, and is responsible for processing feelings and emotions, resulting in attitudes and actions.
