A simple score (ABCD2) to identify individuals at high early risk of stroke after transient ischemic attack.
Neurology
Diagnostic Criteria of Infarction in MRI of the Brain in Acute Stroke
Acute: Subtle low signal (hypointense) on T1, often difficult to see at this stage, and high signal (hyperintense) on spin density and/or T2-weighted and proton density-weighted images starting 8 h after onset; should follow vascular distribution. Mass effect maximal at 24 h, sometimes starting 2 h after onset, even in the absence of parenchymal signal changes. No parenchymal enhancement with paramagnetic contrast agent. Territorial intravascular paramagnetic contrast enhancement of “slow-flow” arteries in hyperacute infarcts; at 48 h, parenchymal and meningeal enhancement can be expected.
Diagnostic Criteria of Infarction in CT Imaging of the Brain in Acute Stroke
Computed tomography (CT) is widely used for early evaluation of acute strokes. Most importantly, CT excludes acute hemorrhage or other diseases mimicking ischemia.
Diagnostic Criteria for Tuberous Sclerosis Complex (TSC)
The diagnostic criteria for tuberous sclerosis complex (TSC) were revised at the Tuberous Sclerosis Complex Consensus Conference, July 1998.
Definite TSC: Two major features or one major feature plus two minor features
Probable TSC: One major feature plus one minor feature
Possible TSC: One major feature or two or more minor features
McDonald Diagnostic Criteria for Multiple Sclerosis (MS)
What Is An Attack?
- Neurological disturbance of kind seen in MS
- Subjective report or objective observation
- 24 hours duration, minimum
- Excludes pseudoattacks, single paroxysmal episodes
Diagnostic Criteria for Parkinson’s Disease (PD)
United Kingdom Parkinson’s Disease Society Brain Bank Diagnostic Criteria for Parkinson’s Disease

Diagnostic Criteria of Paraneoplastic Neurological Disorder (PND) of the CNS
Definite PND
- Classic syndrome with cancer diagnosed within 5 years of neurological symptom development
- Nonclassic syndrome that resolves or significantly improves after cancer treatment
- Nonclassic syndrome with cancer diagnosed within 5 years of neurological symptom development and positive antineuronal antibodies
- Neurological syndrome (classic or not) without cancer and with well-characterized antineuronal antibodies
ICHD-II Diagnostic Criteria for Classical Trigeminal Neuralgia
Classical trigeminal neuralgia
A. Paroxysmal attacks of pain lasting from a fraction of a second to 2 minutes, affecting one or more divisions of the trigeminal nerve and fulfilling criteria B-C
B. Pain has at least 1 of the following characteristics:
Diagnostic Criteria for Myasthenia Gravis
Neuromuscular transmission disorder characterized by fluctuating weakness and fatigability of bulbar and other voluntary muscles without loss of reflexes or impairment of sensation or other neurologic function.
ICHD-II Diagnostic Criteria for Migraine
Migraine without aura
A. At least 5 attacks fulfilling criteria B-D
B. Headache attacks lasting 4-72 hours (untreated or unsuccessfully treated)
C. Headache has at least 2 of the following characteristics:
