More than four and a half years had elapsed before the plaintiffs brought a tort claim founded on an industrial accident in which Gerald Gore (Gore) was injured. Gore is the *646 husband of Judith and the father of Tanya, Robin, and Gerome. The principal question in the case is whether the nature of Gore’s injury was inherently unknowable, and the operation of the three-year statute of limitations 2 suspended, until a diagnosis of depression and organic brain syndrome was made on June 19, 1979. A judge of the Superior Court determined that, upon the facts as presented by affidavits and a stipulation, the statute of limitations had not been tolled. He allowed the defendant’s motion for summary judgment and entered judgments accordingly. Judgments for the defendant were entered, as will appear, on different grounds as to claims brought by the minor plaintiffs.
The facts were as follows. On August 16, 1976, Gore, while working as a mason on a construction job, was hit in the head by a 4" x 4" x 8' timber. Although he was wearing a hard hat, the blow must have been considerable because Gore was told at the Holyoke Hospital, to which he had been taken for examination, that “he had apparently received a bad concussion.” (The quoted phrase is from a report by the psychiatrist who examined Gore on May 31, 1979, and who made the diagnosis on which the plaintiffs rest their action.) Gore displayed no outward physical manifestations of injury, but twenty-four hours after the accident he felt helpless and listless. From that time on Gore was depressed. He consulted a series of physicians. Dr. Smith, the physician who originally examined Gore at the hospital, sent Gore for a neurological work-up which turned up no neurological symptoms. A Dr. Reiss was similarly unable to find a neurological basis for Gore’s difficulties. There followed a trip to the Lahey Clinic. Doctors there, following a medical and psychiatric work-up, diagnosed Gore’s difficulty as anxiety with depression. Psychotherapy with a Dr. Williams followed. He wrote on February 28, 1978, that it was his ‘ ‘ impression that the symptoms are related to [Gore’s] accident.” 3 *647 Dr. Williams posited ‘ ‘residual symptomatology from the blow to the head” and “a compensation neurosis” arising from the accident. On June 6, 1978, Gore underwent a battery of tests at the Neuro-Psychological Testing Laboratory at the Baystate Medical Center. An examining psychologist, Dr. Klepper, gave his diagnostic impression that: “Gerald Gore appears to have a chronic, mild, organic syndrome, associated with brain trauma, affecting the frontal and temporal lobes.”
Still another psychiatric examination of Gore was conducted May 31, 1979, by Dr. Borenstein, who made a written report and diagnosis on June 19, 1979. Dr. Borenstein addressed his report to the plaintiffs’ lawyer, and we may safely infer that it was prepared in anticipation of litigation. The Borenstein diagnosis is the one which the plaintiffs say informed them for the first time of the nature of Gore’s medical condition.
1.
The running of the statute of limitations.
T o the usual rule that a personal injury action accrues at the time the plaintiff is injured,
Dinsky
v.
Framingham,
In the case of disease, it is possible that the disease lies latent and undiscoverable when the fact of some injury from a tort is first known. Asbestos-related disease is an example. So in
Fearson
v.
Johns-Manville Sales Corp.,
Here, however, no distinct disease has turned up. Almost immediately after Gore was hit on the head he became depressive and anxious. He lost no significant time in consulting medical help and more than one physician identified Gore’s condition and linked it to his head injury of 1976. Gore did not work and was listless at home. His wife, therefore, cannot claim that state of “blameless ignorance” which tolls the statute of limitations. See
Urie
v.
Thompson,
When an injury or disease resulting from injury becomes manifest, the statute of limitations does not stay in suspense until the full extent, gravity, or permanence of that same injury or consequential disease is known. So in

2. The claims of the children. At the time of Gore’s injury his children were minors, 4 and ordinarily the statute of limita *650 lions on the claim of each for loss of parental society and emotional distress would not begin to run until each reached the age of majority. G. L. c. 260, § 7.
The possibility of an independent claim for loss of parental society by reason of injuries to a parent was announced in

As to the claims based on emotional distress, assuming, without so deciding, that the plaintiffs’ complaint alleges a substantial consequential physical injury within the meaning of
Dziokonski
v.
Babineau,
Judgments affirmed.
Notes
G. L. c. 260, § 2A, as amended by St. 1973, c. 777, § 1.
The plaintiffs’ action was filed April 30, 1981, and, therefore, not within three years of this relatively specific diagnosis. The Lahey Clinic had earlier — in August, 1977 — diagnosed Gore’s condition as anxiety with depression.
Indeed, at the time of Dr. Borenstein’s report on June 19, 1979, the children were age thirteen, ten, and seven.
