The police spokesman, who spoke on condition of anonymity under police rules, said that "the characteristics of the attack pointed to it being the work of ETA".
Mr. Coviello said in the letter that characteristics of the attack on RSA "indicated that the perpetrator's most likely motive" was to steal security information that could be used to obtain military secrets and intellectual property.
If the civilian population had suffered significant mental breakdown, he wanted to know, what were the characteristics of the attacks that had achieved this effect?
What are the unique characteristics of these attacks, and how can their effects be mitigated?
The characteristics of the attacks varied not only between families but also among individuals in the same family.
Headache diaries make it possible to record prospectively the characteristics of every attack and the use of headache calendars is indicated for evaluating the time pattern of headache, identifying aggravating factors, and evaluating the efficacy of preventive treatment.
These diaries, which are filled in at home by the patients and returned at follow-up visits, allow prospective recording of the characteristics of every attack and therefore more accurate descriptions of the disease; they also make it possible to confirm and/or distinguish between different types of headache in subjects with coexisting forms.
Clinical determinants included the frequency and length of attacks, the proportion of time patients experienced an attack, characteristics of attacks (including degree of fever and other systems involved), the patient/parental and physician global assessment assessed by marking a Likert-like 0 (best) –10 (worst) scale and the Modified Armenian Severity Score [ 24].
We emphasize that it might not be within the reach of an attacker to decide freely about the characteristics of a possible attack to a system.
The aims of this study are (1) to determine the clinical characteristics of headache attacks and to investigate the relevance of associated symptoms such as nausea, vomiting, phonophobia, and photophobia; (2) to investigate other associated symptoms that could improve diagnostic certainty, including osmophobia, dizziness, and vertigo; and (3) to analyze relationships among associated symptoms.
