Amnesia is a deficit in memory caused by brain damage or disease, but it can be caused temporarily by the use of various sedatives and hypnotic drugs. The memory can be either wholly or lost due to the extent of damage, caused. There are two main types of amnesia: anterograde amnesia. Retrograde amnesia is the inability to retrieve information, acquired before a particular date 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 anterograde amnesia cannot remember things for long periods of time; these two types are not mutually exclusive. Case studies show that amnesia is associated with damage to the medial temporal lobe. In addition, specific areas of the hippocampus are involved with memory. Research has shown that when areas of the diencephalon are damaged, amnesia can occur.
Recent studies have shown a correlation between deficiency of RbAp48 memory loss. Scientists were able to find that mice with damaged memory have a lower level of RbAp48 protein compared to normal, healthy mice. In people suffering with amnesia, the ability to recall immediate information is still retained, they may still be able to form new memories. However, a severe reduction in the ability to learn new material and retrieve old information can be observed. Patients can learn new procedural knowledge. In addition, priming can assist amnesiacs in the learning of fresh non-declarative knowledge. Amnesic patients retain substantial intellectual and social skill despite profound impairments in the ability to recall specific information encountered in prior learning episodes; the term is from Ancient Greek, meaning'forgetfulness'. Individuals with amnesia can learn new information if the information is non-declarative knowledge. However, in some situations, people with dense anterograde amnesia do not remember the episodes during which they learned or observed the information.
Some people who suffer from amnesia show abnormal amounts of memory loss and difficulty recalling other people or places. People who recover do not remember having amnesia; some patients with anterograde amnesia can still acquire some semantic information though it might be more difficult and might remain rather unrelated to more general knowledge. H. M. could draw a floor plan of the home in which he lived after surgery though he had not lived there in years. The reason patients could not form new episodic memories is because the CA1 region of the hippocampus was a lesion, thus the hippocampus could not make connections to the cortex. After an ischemic episode following surgery, an MRI of patient R. B. showed his hippocampus to be intact except for a specific lesion restricted to the CA1 pyramidal cells. Some retrograde and anterograde amnesics are capable of non-declarative memory, including implicit learning and procedural learning. For example, some patients show improvement on the pseudorandom sequences experiment as healthy people do.
Therefore, procedural learning can proceed independently of the brain system required for declarative memory. According to fMRI studies, the acquisition of procedural memories activates the basal ganglia, the premotor cortex and the supplementary motor area, regions which are not associated with the formation of declarative memories; this type of dissociation between declarative and procedural memory can be found in patients with diencephalic amnesia such as Korsakoff's syndrome. Another example demonstrated by some patients, such as K. C. and H. M, who have medial temporal damage and anterograde amnesia, still have perceptual priming; those patients did well in the word fragment completion test. There are three generalized categories; the three categories are traumatic events, or physical deficiencies. The majority of amnesia and related memory issues derive from the first two categories as these are more common and the third could be considered a subcategory of the first. Head trauma is a broad range as it deals with any kind of injury or active action toward the brain which might cause amnesia.
Retrograde and anterograde amnesia is more seen from events like this, an exact example of a cause of the two would be electroconvulsive therapy, which would cause both for the receiving patient. Traumatic events are more subjective. What is traumatic is dependent on what the person finds to be traumatic. Regardless, a traumatic event is an event where something so distressing occurs that the mind chooses to forget rather than deal with the stress. A common example of amnesia, caused by traumatic events is dissociative amnesia, which occurs when the person forgets an event that has disturbed them. An example would be a person forgetting a graphic car accident involving their loved ones. Physical deficiencies are different from head trauma because physical deficiencies lean more toward passive physical issues. Among specific causes of amnesia are the following: Electroconvulsive therapy in which seizures are electrically induced in patients for therapeutic effect can have acute effects including both retrograde and anterograde amnesia.

At their twenty-eighth Meeting of the Parties to the Montreal Protocol l held on October 15, 2016 in Kigali, the Parties to the Montreal Protocol on substances that deplete the ozone layer reached an agreement on a gradual reduction in their consumption and production of hydrofluorocarbons. In decision XXVIII / 1, they adopted an amendment to the Protocol ); the Kigali Amendment is a binding international agreement designed to create rights and obligations in international law. The Amendment is only binding on a Party if it has entered into force with respect to that Party As of November 5, 2018, 59 States had ratified the Kigali Ammendment. Many industrial products, including heat pumps that operate on a refrigerant and propellant aerosol s, require non-flammable fluids capable of passing from gaseous state to liquid state and having significant latent heat. Chlorofluorocarbons s were used in these applications, but we discovered in the 1970s the deleterious effect of these gases on the ozone layer, rewarded by a Nobel Prize in Chemistry in 1995.
The Montreal Protocol, signed in 1985 by many states and entered into force in 1989, decided to phase out CFCs. The use of hydrofluorocarbons s developed as a replacement. However, if these gases save the ozone layer, they are powerful greenhouse gases, their lifespan in the atmosphere is quite short, but they filter infrared strongly: for example, HFC-23 has a global warming potential at 100 years 12400. It therefore appears that eliminating emissions of these gases could limit, in the short term, global warming; the Montreal Protocol creates a separate regime for developing countries. The Kigali Accord, on the other hand, divides states into 4 groups: Parties "article 5 - Group 1" Parties "Article 5 - Group 2": Bahrain, Iran, Kuwait, Pakistan, Saudi Arabia, the United Arab Emirates.
