  Extrapyramidal Signs   (Site not responding. Last check: )
However, in many instances, the cause of extrapyramidal signs in patients with Alzheimer's disease is not clear.
The researchers used autopsies to confirm the findings in the Alzheimer's cases, exploring sections of the substantia nigra and basal ganglia for pathological changes, since pathology in these areas is known to produce a variety of extrapyramidal signs.
They found that degenerative changes in the substantia nigra, especially neurofibrillary tangles, correlated with the presence of extrapyramidal signs before death, says Dr. Liu, staff associate in the pathology department's neuropathology division.

  Extrapyramidal system - Biocrawler   (Site not responding. Last check: )
In human anatomy, the extrapyramidal system is a neural network located in the brain that is part of the motor system involved in the coordination of movement.
The extrapyramidal system can be affected in a number of ways, which are revealed in a range of extrapyramidal symptoms such as akinesia and akathisia.
Extrapyramidal side effects (EPS) are the various movement disorders suffered as a result of taking antipsychotic (neuroleptic) drugs, which are often used to control psychosis, especially schizophrenia.

 Vitamin B12 deficiency presenting with an acute reversible extrapyramidal syndrome Kumar Sudhir Neurol India
The present report highlights an unusual presentation of vitamin B12 deficiency- acute onset extrapyramidal syndrome in a 55-year-old man. The patient presented with a 10-day history of slowness of all activities including a slow gait, mild tremors of hands and low volume speech.
Extrapyramidal involvement due to vitamin B12 deficiency in adults is rare and previously reported features include myoclonus-like involuntary movements[3] and chorea and focal dystonia.
The mechanism of extrapyramidal involvement in vitamin B12 deficiency is incompletely understood.

 Extrapyramidal system . Enpsychlopedia
Extrapyramidal tracts originate from different part of the brain as the red nuclear, reticular formation.
Extrapyramidal side effects (EPS) are the various movement disorders such as tardive dyskinesia suffered as a result of taking dopamine antagonists, usually antipsychotic (neuroleptic) drugs, which are often used to control psychosis, especially schizophrenia.
Extrapyramidal symptoms can also be caused by brain damage, as in athetotic cerebral palsy, which is involuntary writhing movements caused by perinatal brain damage.

 News - Risperidone and Olanzapine May Reduce Risk of Extrapyramidal Symptoms
Risperidone and olanzapine also were associated with a reduced risk of extrapyramidal symptoms irrespective of previous use of antiparkinsonian medication.
On the other hand, was no significant difference in the likelihood of developing extrapyramidal symptoms among those taking risperidone and who had a history of such symptoms compared to those taking haloperidol: the relative risk was 1.30.
They conclude that risperidone and olanzapine seem to be associated with a reduced risk of extrapyramidal symptoms compared to haloperidol in patients with similar treatment histories.

 Extrapyramidal Side Effects
Extrapyramidal symptoms are caused by dopamine blockade or depletion in the basal ganglia; this lack of dopamine often mimics idiopathic pathologies of the extrapyramidal system.
Less recognized is that extrapyramidal symptoms are also associated with certain non-antipsychotic agents, including some antidepressants, lithium, various anticonvulsants, antiemetics and, rarely, oral-contraceptive agents.
Extrapyramidal symptoms caused by these agents are indistinguishable from neuroleptic-induced extrapyramidal symptoms.

 News - Olanzapine Comparable to Haloperidol, Causes Fewer Extrapyramidal Symptoms
Intramuscular (I.M.) olanzapine appears to be comparable to I.M. haloperidol for reducing the symptoms of acute schizophrenia during the first 24 hours of treatment, according to the findings of a new randomised trial.
In the current report, the researchers describe additional findings from the same study on the antipsychotic efficacy and extrapyramidal safety of I.M. olanzapine and I.M. haloperidol during the first 24 hours of treatment of acute schizophrenia.
According to the researchers early clinical improvement predicts a more favourable eventual outcome, therefore, "the rapid alleviation of agitation and early reduction of positive symptoms during treatment with IM olanzapine could improve the prognosis of some patients with schizophrenia," they suggest.

 extrapyramidal disorder
You are correct in assuming that extrapyramidal disorder is an umbrella term for a range of disorders, however this is by no means a rare type of disorder.
This refers to diseases which do not involve the pyramidal tract which is the nerve projection frequently involved in strokes which cause paralysis on one side of the body.
The most common extrapyramidal disorder is Parkinson’s disease which is very common, other less common disorders include progressive supranuclear palsy, Huntingtons chorea, and various diseases of the cerebellum.

 Clozapine-associated extrapyramidal reaction -- Elliott et al. 34 (5): 615 -- The Annals of Pharmacotherapy
OBJECTIVE: To report a case of extrapyramidal reaction associated with a dosage increase of clozapine.
At the time of the adverse reaction, he was prescribed clozapine 450 mg/d, vitamin E 400 IU three times daily, aspirin 325 mg/d, and acetaminophen, milk of magnesia, and Maalox as needed.
DISCUSSION: Although the risk of extrapyramidal symptoms (EPS) is significantly lower with clozapine than with conventional agents, elevated clozapine blood concentrations have been reported to cause EPS; other reports have cited severe dystonias and dyskinesias on abrupt clozapine withdrawal.

Extrapyramidal symptoms were evaluated using the Simpson-Angus Scale (SAS), the Barnes Akathisia Rating Scale (BARS), adverse event reports and anticholinergic drug usage.
Haloperidol induced a significantly higher incidence (p < 0.001) of akathisia (33.3% versus 5.9%), tremor (30.3% versus 7.8%), and extrapyramidal syndrome (35.4% versus 5.9%) than quetiapine.

The likelihood of acute extrapyramidal reactions, such as akathesia, dystonia, and neuroleptic-induced parkinsonism is quite high, with close to 90% of all classic antipsychotic users developing these reactions.
The potential benefits of clozapine are widespread, including the treatment of both positive and negative symptoms in psychosis, the reduced risk of extrapyramidal side effects and tardive dyskinesia, and the seemingly higher compliance with medication use as opposed to the classical antipsychotics.
Likewise, the incidence of acute extrapyramidal reactions and tardive dyskinesia seems to be much lower.
